We consider the unital Banach algebra$\ell ^{1}(\mathbb{Z}_{+})$and prove directly, without using cyclic cohomology, that the simplicial cohomology groups${\mathcal{H}}^{n}(\ell ^{1}(\mathbb{Z}_{+}),\ell ^{1}(\mathbb{Z}_{+})^{\ast })$vanish for all$n

This chapter is based on work done for more than 40 years at Universite Laval, in mathematics courses for future secondary-level mathematics teachers. This work was initiated by Bernard Hodgson, in collaboration with colleagues in the Department of M

In this paper, we consider the path semigroup l 1 -algebra for a quiver and the inverse semigroup l 1 -algebra of a quiver, the latter of which can be used in the construction of Cuntz–Krieger algebras. The main objectives of the paper are to deter

Let S be a Rees semigroup, and let `(S) be its convolution semigroup algebra. Using Morita equivalence we show that bounded Hochschild homology and cohomology of `(S) are isomorphic to those of the underlying discrete group algebra.

Let □ = l 1 (ℬ) be the semigroup algebra of ℬ, the bicyclic semigroup. We give a resolution of l ∞ (ℬ) which simplifies the computation of the cohomology of l 1 (ℬ) dual bimodules. We apply this to the dual module l ∞ (ℬ) and show tha

In this paper, we investigate the higher simplicial cohomology groups of the convolution algebra ℓ1(S) for various semigroups S. The classes of semigroups considered are semilattices, Clifford semigroups, regular Rees semigroups and the additive se

Describing the minimal mathematical content knowledge needed for secondary school teachers is not the most useful way to approach the mathematical preparation of teachers. Rather, focusing on the doing of mathematics, on the quality of their engageme

Let A = l 1 (Z + ) be the unital semigroup algebra of N. We show that the cyclic cohomology groups HC n (A,A') vanish when n is odd and are one dimensional when n is even (n ≥ 2). Using Connes' exact sequence, these results are used to show that th
