Nonabelian cohomology is a branch of mathematics that studies the cohomological properties of nonabelian structures, particularly in the context of group theory and algebraic geometry. It generalizes classical cohomology theories to contexts where the groups involved do not necessarily obey the commutative property, hence the term "nonabelian.
