“Finite part of operator K-theory” II
This is a sequel to an earlier post on the Weinberger-Yu paper referenced below. Weinberger and Yu state their main conjecture as follows. Let \(G\) be a discrete group. Conjecture 1.1. If \(\{g_1, ·...

Continuing this series (earlier posts here, here and here) on the paper of Weinberger and Yu, I’m expecting to make two more posts: this one, which will say something about the class of groups for...

After a busy day giving final exams in the MASS program it was nice to learn today that my paper with Paul Siegel about sheaves of C*-algebras has appeared in the Journal of K-Theory. The link for the...

I gave a talk in our seminar yesterday which arises from trying to understand the paper of Chang, Weinberger and Yu (Chang, Stanley, Shmuel Weinberger, and Guoliang Yu. “Positive Scalar Curvature and a...
