On the cohomology and the Chow ring of the classifying space of PGL_p

Angelo Vistoli

Published 2005-05-03, updated 2005-07-03Version 2

We investigate the integral cohomology ring and the Chow ring of the classifying space of the complex projective linear group PGL_p, when p is an odd prime. In particular, we determine its additive structure completely, and we reduce the problem of determing its multiplicative structure to a problem in invariant theory.

Comments: I have corrected several typos, added some references, and slightly expanded the introduction
