On the cycle map of a finite group
arXiv:1410.5178 · doi:10.2140/akt.2017.2.47
Abstract
Let p be an odd prime number. We show that there exists a finite group of order p^{p+3} whose the mod p cycle map from the mod p Chow ring of its classifying space to its ordinary mod p cohomology is not injective.
