SOME RESULTS ON THE SECOND BOUNDED COHOMOLOGY OF A PERFECT GROUP
Park, Hee-Sook;

Abstract
For a discrete group G, the kernel of a homomorphism from bounded cohomology $\small{\hat{H}^*(G)}$ of G to the ordinary cohomology $\small{H^*(G)}$ of G is called the singular part of $\small{\hat{H}^*(G)}$. We give some results on the space of the singular part of the second bounded cohomology of G. Also some results on the second bounded cohomology of a uniformly perfect group are given.
