Abstract: The aim of this paper is to study the structure of the Hochschild co-homology ring of Brauer tree algebras. We explicitly describe the evencohomology rings by generators and relations. This generalizes results of[Ho[] on the Hochschild cohomology of blocks of modular group algebraswith cyclic defect groups.References[Ho[] Holm, T.: The even Hochschild cohomology ring of a block with cyclicdefect group.
