• May 20, 2008 at 12:00, in Gilkey 115: (Topology Seminar) Bill Kronholm, Universisty of Oregon, Introduction to Equivariant Topology

  The study of symmetries of topological spaces can be approached by considering the action of a group on the space. In this equivariant setting, we can study homotopy, homology, and cohomology, each of which has a slightly different feel than in the usual nonequivariant setting. In my work, I consider the action of the group Z/2Z on spaces and study their cohomology. In this talk, I'll show some of my computations of the equivariant cohomology of real projective spaces and Grassmann manifolds.

• May 30, 2008 at 12:00, in Gilkey 113: (Applied Mathematics and Computation Seminar) Son-Young Yi, Numerical methods for saddle point problems

  Large linear systems in saddle point form arise in many applications throughout computational science and engineering. The mixed finite element methods in fluid and solid mechanics are typical examples of saddle point problems. The indefiniteness of their matrices makes it hard to solve the systems. In this talk, we will present various numerical solution techniques for this type of systems, with an emphasis on iterative methods and preconditioning techniques for large and sparse problems. This expository talk will be useful to graduate students as an introduction to this rich and important subject.
