                 Special Session on Applications of 
               Computational Topology and Algebra to 
                    Engineering and Mathematics

This is a call for papers in the area of computational topology and 
algebra as applied to solving problems in the following areas:


   o  Solutions of ordinary and partial differential equations 
      through the use of differential Groebner bases and/or 
      symmetry methods.

This includes, for example

   1. Differential Groebner basis techniques in general.
   2. Resolutions of operators using differential Groebner 
      basis techniques.
   3. Calculation of symmetries of systems of differential
      equations.
   4. Combined use of symmetries and differential Groebner
      basis techniques.


   o  The use of algebraic techniques for applied mathematics 
      and numerical computations.

This includes, for example

   1. The use of symbolic computation in the finite element
      and finite difference methods.
   2. The use of symbolic computation to precondition problems 
      for more efficient numeric solution.
   3. The use of Lie algebra techniques in applied mathematics.
   4. Symbolic computation in mathematical physics (R-matrices,
      quantum Yang-Baxter equation, physical systems, etc).
   5. Algebraic methods in the theory of interpolation.


   o  Applications of topology and algebra to problems in engineering 
      and science.

This includes, for example

   1. Homology techniques in computer-aided design.
   2. Applications of computational topology to robotics.
   3. Applications of computational topology and algebra
      to networks and communication systems.
   4. Applications of computational topology to biology
      chemistry and other sciences.
