MAT 539 Algebraic Topology Instructor Sorin Popescu (office: Math 4-119, tel. 632-8358, e-mail sorin@math.sunysb.edu Prerequisites A basic introduction to geometry/topology, such as MAT 530 and MAT 531 Textbook Differential forms in algebraic topology , by Raoul Bott and Loring W. Tu, GTM , Springer Verlag 1982. The guiding principle of the book is to use differential forms and in fact the de Rham theory of differential forms as a prototype of all cohomology thus enabling an easier access to the machineries of algebraic topology in the realm of smooth manifolds. The material is structured around four core sections: de Rham theory, the Cech-de Rham complex, spectral sequences, and characteristic classes, and includes also some applications to homotopy theory.

Home Introduction Posters Problems ... The Design Team Algebraic Geometry and Topology How can we tell if two shapes are the same? What if these shapes are not two-dimensional but, say, thirty-three dimensional? Saying if two shapes are the same is a very difficult question, but it turns out that telling if two shapes are not the same is a slightly easier question! What do I mean by this? Suppose you have to meet a stranger at the airport. You've never met this person in your life; you don't want to look silly standing there holding a sign. You know the person you are looking for is five foot five, dark haired, wearing red. Suppose you're at the airport and a six foot blonde giant walks out in a green cowboy outfit. You know this is not the person you are looking for. Now suppose, a very neat five foot five brunette walks out wearing a stylish red jumper. Do you know if this is the person you are looking for? When it comes to wild and wacky shapes it is not easy to attach labels like "red" or "dark haired". This is where algebra comes in. Abstract algebra (like, for example, groups) can be "attached" to some spaces in a natural way; they can function as labels like "red". If two spaces have different algebraic labels, they must be different.

65. Algorithms For The Fixed Point Property A survey of various algorithms used to determine if a given ordered set has the fixed point property, that is, whether it has a fixed point free orderpreserving self-map. Algorithms using the methods of algebraic topology are compared with other techniques. http://www.csi.uottawa.ca/ordal/papers/schroder/FINSURVE.html

Next: Contents Algorithms for the Fixed Point Property e-mail: schroder@huajai.cs.hamptonu.edu July 29, 1996 Abstract. This survey exhibits various algorithms to decide the question if a given ordered set P has the fixed point property resp. if P has a fixed point free order-preserving self-map. While a depth-first search algorithm for a fixed point free map is easily written it is also quite inefficient. We discuss a reduction algorithm by Xia which can be used to speed up the search for a fixed point free self map. The ideas used in creating this algorithm show close connections to two problems: the decision whether an ordered set has a fixed point free automorphism and the decision whether a given r -partite graph has an r -clique. The latter two problems are shown to be NP-complete using the work of Goddard, Lubiw and Williamson. The problem to decide whether a given finite ordered set has a fixed point free order-preserving self map has recently been shown to be NP-complete, thus showing that the above close connection is not by accident. Retraction theorems leading to dismantling algorithms are another approach to the problem. We present the classical dismantling procedure by Rival and extensions by Fofanova, Li, Milner, Rutkowski and the author. These theorems give a polynomial algorithm to decide if an ordered set has the fixed point property for some nice classes of ordered sets (height 1, width 2), and structural insights for other classes (chain-complete ordered sets with no infinite antichains, sets of (interval) dimension 2). The related issue of uniqueness of cores gives an insight into Birkhoff's problem regarding cancellation of exponents. Walker's relational fixed point property for which the analogous problem has a very satisfying solution also is discussed.

66. The Kenzo Program. A computer program for computational algebraic topology. http://www-fourier.ujf-grenoble.fr/~sergerar/Kenzo/

Overview. The Kenzo program is the last version (16000 Lisp lines, July 1998) of the CAT (= Constructive Algebraic Topology) computer program. Kenzo is also the name of my cat . The Kenzo program is a joint work with Xavier Dousson. The previous version EAT (May 1990) was a joint work with Julio Rubio. The Kenzo program is significantly more powerful than EAT, from several points of view. On one hand, for the computations which could be done with the EAT program, the computing times are divided by a factor generally between 10 and 100. The reasons are multiple and it is not obvious to decide what the most important are. Some are strictly technical; for example the numerous multi-degeneracy operators are now coded with a unique integer, using an amusing binary trick: various tests show much progress has been obtained in this way. Other reasons are strictly mathematical; for example another choice for the Eilenberg-Zilber homotopy operator leads in the Kenzo program to Szczarba's universal twisting cochain; in the EAT program we used Shih's universal twisting cochain; experience shows that Szczarba's cochain is considerably more efficient than Shih's one. It is a major mathematical problem to understand

67. Algebraic Topology Although algebraic topology can be considered, by and large, as a creation of algebraic topology evolved slowly during the course of the 19th century. http://www.maths.lth.se/matematiklu/personal/jaak/Alg-Top.html

Algebraic Topology Brief historical introduction Although algebraic topology can be considered, by and large, as a creation of the 20th century, it has a long pre-history. It is generally considered to have its roots in Euler's polyhedron theorem (1752). This is the relation $$ E+F=K+2$$ where $E$ is the number of vertices, $K$ the number of edges, and $F$ the number of faces. In the first half of this century many mathematicians defined homology for more and more extended classes of topological spaces. Thus, for instance singular homology was first defined by Lefschetz in 1933. Finally, in 1945, Eilenberg and Steenrod developed an axiomatic approach to homology. It turned out that within the class of all topological spaces the Eilenberg and Steenrod axioms uniquely characterize singular homology. A parallel development took place in homotopy. Thus, higher homotopy groups were defined by Hurewicz in 1935 and their properties were developed. In the 1950's several new concepts were invented such as cobordism and $K$-theory. The course will be based mainly on Greenberg and Harper's book quoted below.

Contact Geometry and Algebraic Topology In many respects, the latter half of the 20th Century has been a golden age of Geometry and Topology, with spectacular advances in the study of manifolds (particularly in dimension 4), Global Analysis including Index Theory, complex manifolds and Algebraic Geometry, including its applications in Number Theory. Increasingly, strong connections with integrable system theory and global aspects of differential equations as well as the remarkable two-way flow of ideas between Geometry and Theoretical Physics are dominating developments. Algebraic Topology has developed important machinery such as cohomology theories including ordinary cohomology, K -theory, cobordism and elliptic cohomology. These are often of use in geometric situations, as well as within Algebraic Topology itself which tends to study much less `rigid' geometric situations than Geometers do. There have also been significant interactions with many areas of Algebra, and indeed much of Algebraic Topology can be viewed as `applied algebra' as well as being a major source of innovative algebraic ideas. Departmental research activity in Geometry and Topology occurs in the following areas.

Math 177a Special Topics Algebraic Topology Professor Francis Su x73616, su @ math.hmc.edu Office Hours: WED 1-2:30pm. Course Content: This course is an introduction to algebraic and combinatorial topology, with an emphasis on simplicial and singular homology theory. A major theme in the course will be the connection between combinatorial and topological concepts. Topics will include simplicial complexes, simplicial and singular homology groups, exact sequences, chain maps, diagram chasing, Mayer-Vietoris sequences, Eilenberg-Steenrod axioms, Jordan curve theorem, and additional topics as time permits. This is standard first-year graduate material in pure mathematics. Text: Munkres, Elements of Algebraic Topology . Doing the reading will be essential for success in this course. Prerequisites: Analysis I (Math 131), Algebra I (Math 171), and Topology (Math 147, or topology summer readings), or the permission of the instructor. I will try to set up a few extra sessions to meet with those who did the summer readings. A note about the course: Expect this course to be challenging, but also quite rewarding, as you see the interplay between algebra, topology, combinatorics, and analysis. I will run this course more like a graduate course. As such, I will expect a certain level of mathematical maturity. This means that sometimes I will not prove simple statements in class; you may have to work out some details for yourself or by doing the reading. My focus will be on proving the larger theorems and providing perspective on the material.

Minicourse on Geometric and Topological Methods in Concurrency Theory associated to LATIN 2002 Venue: Cancun, Mexico Dates: April 2 - April 6, 2002 Scope of the Minicourse Mathematical methods have always played a significant role in theoretical computer science: Discrete mathematics , in particular graph theory and ordered structures; logics , i.e., proof theory for all kinds of logics, classical, intuitionistic, modal etc.; and category theory , cartesian closed categories, topoi etc., have become undispensable tools. Also general topology has been used for instance in denotational semantics, with relations to ordered structures in particular. Recently, ideas and notions from mainstream geometric and algebraic topology have entered the scene in Concurrency Theory and Distributed Systems Theory. They have been applied in particular to problems dealing with the coordination of multi-processor and distributed systems. Techniques borrowed from higher-dimensional algebraic and geometric topology yield concepts, results and algorithms that seemed unreachable with traditional approaches: Techniques relying on simplicial combinatorial topology have led to new theoretical bounds concerning computability of fault-tolerant distributed protocols.

Contents Encyclopedia - Algebraic topology Algebraic topology is a branch of mathematics in which tools from abstract algebra are used to study topological spaces The goal is to take topological spaces, and further categorize them by mapping them to groups , which have a great deal of structure. Two major ways in which this can be done are through fundamental groups , or homotopy, and through homology /cohomology groups. Fundamental groups give us crucial information about the structure of a topological space, but they are often nonabelian and can be difficult to work with. Homology/Cohomology groups, on the other hand, are abelian, and in many important cases even finitely generated. Finitely generated abelian groups can be completely classified and are particularly easy to work with. Several nice results follow immediately from working with finitely generated abelian groups . If an n -th homology group of a simplicial complex has torsion, then the complex is nonorientable . The free rank of the n -th homology group of a simplicial complex is equal to the n -th Betti number[?]
