Isomorphisms, Moduli, and Cohomological Dimension for Twisted Triangular Banach Algebras

Sara Behnamian, Fatemeh Fogh

We introduce and study twisted triangular Banach algebras T_sigma(A,B;X), built from Banach algebras A,B, a Banach A-B bimodule X, and a pair of automorphisms sigma=(sigma_A,sigma_…
