报告摘要：This talk focuses on investigating the cohomology of operator algebras associated with the free semigroups, with left regular free semigroup algebras and non-commutative disc algebras serving as two typical examples. We establish that all derivations are automatically continuous. By a novel computational approach, we demonstrate that the first Hochschild cohomology groups of non-commutative disc algebras are zero.
