HOCHSCHILD COHOMOLOGY AND FUNDAMENTAL GROUPS OF INCIDENCE ALGEBRAS

The aim of this paper is to report on some computations of Hochschild cohomology and fundamental groups of incidence algebras.

Connected gradings and the fundamental group

The main purpose of this paper is to provide explicit computations of the fundamental group of several algebras. For this purpose, given a
