= Banach algebra cohomology
{wiki=Banach_algebra_cohomology}
Banach algebra cohomology is a branch of functional analysis and abstract algebra that studies Banach algebras using the techniques of cohomology. It provides a way to investigate the structure of Banach algebras and their representations through the lens of cohomological methods, which originated in algebraic topology. \#\#\# Basic Concepts: 1. **Banach Algebras**: A Banach algebra \\( A \\) is a complete normed algebra over the field of complex or real numbers.
