A SpinC-manifold is a C\infty manifold with a given structure which is slightly stronger than an orientation. A Spin C manifold has a Dirac operator. This is a first order elliptic differential operator. The (equivariant) indices of these Dirac...

This talk will give a brief history of K-theory.

A number of well known problems (Mackey analogy, Parthasarathy-Atiyah-Schmid construction of the discrete series, Novikov conjecture, stable Gromov-Lawson-Rosenberg conjecture, Kadison-Kaplansky conjecture) are contained in the issue of...
