Cohomological invariants are tools used in algebraic topology, algebraic geometry, and related fields to study the properties of topological spaces, algebraic varieties, or other mathematical structures through their cohomology groups. Cohomology provides a way to classify and distinguish topological spaces by associating algebraic invariants to them.
