SUMMARY:Geometry and Topology Seminar | Ergun Yalcin | Free Actions on\nPro
 ducts of Real Projective Spaces
CLASS:PUBLIC
DESCRIPTION:ERGUN YALCIN (BILKENT UNIVERSITY AND UNIVERSITY OF WATERLOO) \n
 \n_Free Actions on Products of Real Projective Spaces_ \nThere are many co
 njectures on restrictions on finite groups that can\nact freely on a topol
 ogical space with prescribed homotopy type. The\nmost famous of these conj
 ectures is the rank conjecture\, which claims\nthat if an elementary abeli
 an p-group of rank r acts freely on a\nproduct of k spheres\, then r is le
 ss than or equal to k. In 1983\,\nCusick made a similar conjecture for fre
 e actions on products of real\nprojective spaces. We recently solved the h
 omotopy-theoretic version\nof Cusick’s conjecture. I will explain some o
 f the main ideas used\nin the proof of this conjecture\, after introducing
  the necessary\nbackground. \nMC 5417
