Text only Department of Mathematics Home Research > Geometry and Algebraic Topology Home Research Algebra Analysis ... 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.

28th Autumn School in Algebraic Geometry Equivariant intersection theory Lukecin, Poland, September 11th - September 17th, 2005 Teachers: Andrew Kresch (Warwick, UK) and Angelo Vistoli (Bologna, Italy) Program: The subject of our lectures will be equivariant intersection theory. To any smooth complex algebraic variety X one associates two important rings, the Chow ring A(X) and the integral cohomology ring H(X). If G is a linear algebraic group acting on a complex smooth variety X, there are variants of these, called the equivariant Chow ring A_G(X) and the equivariant cohomology ring H_G(X). We will give an elementary introduction to the theory, focusing on examples. We will describe applications in algebraic geometry, to the calculations of Chow rings of important moduli spaces, to questions in representation theory, and to enumerative geometry and Gromov-Witten theory. Prerequisites: Basic knowledge of algebraic geometry. A previous acquaintance with cohomology would be useful, but not indispensable. Preliminary reading list: W. Fulton

27th Autumn School in Algebraic Geometry Algebraic geometry and derived categories Lukecin, Poland, September 19th - September 25th, 2004 Teachers: Andrei Caldararu (Philadelphia, US) and Miles Reid (Warwick, UK) Program: An introduction to algebraic geometry featuring derived categories and some of their applications. A large fraction of the material should be accessible to beginning graduate students with the appropriate motivation. Plan of Caldararu's lectures: I will present a mild introduction to derived categories, attempting to avoid the technical details of their inner workings. Main topics to be covered will hopefully include Grothendieck-Serre duality, a description of the derived category of P^n (the Beilinson construction), the criterion of Mukai-Bondal-Orlov-Bridgeland for when an integral transform is an equivalence, equivalences of Fanos and general type varieties (a la Bondal-Orlov), Mukai's equivalence between the derived category of an abelian variety and that of its dual, and some topics connected to Hochschild homology and cohomology, maybe in connection with Kontsevich's Homological Mirror Symmetry conjecture. Prerequisites: Chapters 2,3 of Hartshorne (especially Serre duality), some elementary algebraic topology

Macaulay A system for computation in algebraic geometry and commutative algebra This page is www.math.columbia.edu/~bayer/Macaulay Description Macaulay is a computer algebra system for mathematical computations in algebraic geometry and commutative algebra. At its core is a carefully tuned implementation of Grobner basis methods for manipulating systems of polynomial equations. Macaulay's user base consists largely of academic researchers and graduate students. It consists of roughly 30,000 lines of C code, documentation, and contributed scripts in Macaulay's command language (which has been dubbed affectionately by some users as "algebraic machine language").

visualization of real algebraic geometry Home Download Documentation Gallery ... Screenshots What is surf surf is a tool to visualize some real algebraic geometry: plane algebraic curves, algebraic surfaces and hyperplane sections of surfaces. surf is script driven and has (optionally) a nifty GUI using the Gtk widget set. The algorithms should be stable enough not to be confused by curve/surface singularities in codimension greater than one and the degree of the surface or curve. This has been achieved quite a bit. We have drawn curves of degree up to 30 and surfaces of degree up to 20 successfully. However, there are examples of curves/surfaces of lower degree where surf fails to produce perfect images. This happens especially if the equation of the curve/surface is not reduced. Best results are achieved using reduced equations. On the other hand, surf displays the Fermat-curves accurately for degree up to 98. surf is free software distributed under the GNU General Public License (GPL).
