These pages contain usenet clippings, web pointers, lecture notes, research excerpts, papers, abstracts, programs, problems, and other stuff related to discrete and computational geometry. Some of it is quite serious, but I hope much of it is also entertaining. The main criteria for adding something here are that it be geometrical (obviously) and that it not fit into my other geometry page, Geometry in Action , which is more devoted to applications and less to pure math. I also have another page on non-geometrical recreational math Junk sorted into piles All the junk in one big pile New junk ... UC Irvine Semi-automatically filtered from a common source file.

111. Ricci: A Mathematica Package For Doing Tensor Calculations In Differential Geome A Mathematica package for doing tensor calculations in differential geometry and general relativity. http://www.math.washington.edu/~lee/Ricci/

Ricci A Mathematica package for doing tensor calculations in differential geometry Version 1.51 Last Updated June 28, 2004 Ricci is a Mathematica package for doing symbolic tensor computations that arise in differential geometry. It has the following features and capabilities: Manipulation of tensor expressions with and without indices Implicit use of the Einstein summation convention Correct manipulation of dummy indices Display of results in mathematical notation, with upper and lower indices Automatic calculation of covariant derivatives Automatic application of tensor symmetries Riemannian metrics and curvatures Differential forms Any number of vector bundles with user-defined characteristics Names of indices indicate which bundles they refer to Complex bundles and tensors Conjugation indicated by barred indices Connections with and without torsion Limitations: Ricci currently does not support computation of explicit values for tensor components in coordinates, or derivatives of tensors depending on parameters (as in geometric evolution equations or calculus of variations), although support for these is planned for a future release. Ricci also has no explicit support for general relativity, or for other mathematical physics or engineering applications, and none is planned. If you are interested in such support, I recommend that you consider the commercial package MathTensor, which is far more extensive than Ricci, and provides all these capabilities and more. MathTensor is available from

Home About us Committees Programme ... Web mail The 6th International Pure Mathematics Conference 2005 (6th IPMC 2005) is a thematic conference on Algebra, Analysis, Geometry and Mechanics. It will be held in Islamabad from 20th to 22nd August 2005. It will provide a stimulating opportunity to meet experts from various countries in a variety of branches of Algebra, Analysis, Geometry, and Mechanics. The entire conference is organized under one roof at a four-star hotel in the modern, peaceful, and beautiful federal capital of Pakistan located at the footsteps of the scenic Margalla Hills. There will be free housing and lodging for foreign participants. Several recreational trips will be organized in and around Islamabad introducing the unique local and multi-ethnic culture. The pre-registration is now complete. We are looking forward to making your stay in Islamabad a memorable one. We are also trying to arrange for the conference proceedings to be published by an international publisher. Contact: mssaeed@ma.hw.ac.uk

Greetings. This site has been taken down as I have not been active with Zenith for some time. I still value it and use it for myself, but I am not serving as a practitioner at this time as I am currently pursuing other avenues of service. Zenith is a wonderful experience and I encourage you to seek out a practitioner in your area. In Tennessee, you can contact Carol Bowling or Jen Hoeft . In Canada, you can contact Deborah Sky King . Any of these people can also help you find practioners located around the world. I wish you infinite love, peace and joy on your journey to Self. Tonua G. Brown

117. Algebraic Areas Of Mathematics Topics include number theory, groups and sets, commutative rings, algebraic geometry, and linear algebra. http://www.math.niu.edu/~rusin/known-math/index/tour_alg.html

Search Subject Index MathMap Tour ... Help! Algebraic Areas of Mathematics Return to start of tour Up to The Divisions of Mathematics The algebraic areas of mathematics developed from abstracting key observations about our counting, arithmetic, algebraic manipulations, and symmetry. Typically these fields define their objects of study by just a few axioms, then consider examples, structure, and application of these objects. We have included here the combinatorial topics and number theory ; each is arguably a distinctive area of mathematics but (as the MathMap suggests) these parts of mathematics, shown in shades of red, share definite affinities. The list on this page includes a rather large number of fields in the MSC scheme. It is also common to interpret the phrase "abstract algebra" in a more narrow sense - to view it as the fields obtained by adding successive axioms to describe the objects of study. Arguably then, abstract algebra is limited to sections 20 and 22 (Group Theory), 13, 16, and 17 (Ring Theory), 12 (Field Theory), and 15 (Linear Algebra), taken in this way as a succession from fewest to most restrictive sets of axioms. The use of algebra is pervasive in mathematics. This particularly true of group theory - symmetry groups arise very naturally in almost every area of mathematics. For example, Klein's vision of geometry was essentially to reduce it to a study of the underlying group of invariants; Lie groups first arose from Lie's investigations of differential equations. It is also true of linear algebra - a field which, properly construed, includes huge portions of Numerical Analysis and Functional Analysis, for example hence that field's central position in the MathMap.

118. EDGE A TMR network. Structure, activities, news and resources. http://edge.imada.sdu.dk/

EDGE EDGE information Welcome Structure Activities Positions available ... About this homepage EUROPEAN DIFFERENTIAL GEOMETRY ENDEAVOUR EDGE aims to encourage and facilitate research and training in major areas of differential geometry, which is a vibrant and central topic in pure mathematics today. A significant theme which unites the areas that are the subject of this endeavour is the interface with other disciplines, both pure (topology, algebraic geometry) and applied (mathematical physics, especially gauge theory and string theory). The members of EDGE are geometers in mathematical centres spreading among most European countries. These centres are grouped into nine geographical nodes which are responsible for the management of joint research projects and for the training of young researchers through exchange between the EDGE groups. The following are some of the common mathematical themes that underlie and unify the tasks to be addressed by EDGE. Another unifying theme is the use of analytical and differential-geometric methods in attacking problems whose origin is not in differential geometry per se. These methods will be used by researchers throughout the network to investigate a wide variety of problems in related areas of mathematics including topology, algebraic geometry, and mathematical physics. In algebraic geometry, for example, there are a number of problems that are best attacked with `transcendental methods'. In some cases, the research concerns correspondences between differential-geometric and algebraic-geometric objects (as in the Hitchin-Kobayashi correspondence and its generalizations).
