THE CYCLIC AND SIMPLICIAL COHOMOLOGY OF THE BICYCLIC SEMIGROUP ALGEBRA

The Quarterly Journal of Mathematics, 2010
Let \(A=\ell^1(B)\) be the semigroup algebra of \(B\), the bicyclic semigroup. In [\textit{S. Bowling} and \textit{J. Duncan}, Semigroup Forum 56, No. 1, 130--145 (1998; Zbl 0910.46055)], the first simplicial cohomology group \(H^1(A,A^*)\) was shown to be isomorphic to \(\ell^\infty(\mathbb{N})\).

The operator equation TS = 1 and representations of l¹ of the bicyclic semigroup

Proceedings of the Royal Society of Edinburgh: Section A Mathematics, 1977
SynopsisThe operator equation TS = 1 is studied for power bounded operators T, S on Hilbert space, and its relation to *—representations of the bicyclic semigroup is explored.
