Vanishing of the first $(\sigma, \tau)$-cohomology group of triangular Banach algebras

Methods Funct. Anal. Topology 14 (2008), no. 4, 351-360

In this paper, we define the first topological $(\sigma,\tau)$-cohomology group and examine vanishing of the first $(\sigma,\tau)$-cohomology groups of certain triangular Banach algebras. We apply our results to study the $(\sigma,\tau)$-weak amenability and $(\sigma,\tau)$-amenability of triangular Banach algebras.
