Difference between Cohomology and Universal coefficient theorem

Cohomology vs. Universal coefficient theorem

In mathematics, specifically in homology theory and algebraic topology, cohomology is a general term for a sequence of abelian groups associated to a topological space, often defined from a cochain complex. In algebraic topology, universal coefficient theorems establish relationships between homology and cohomology theories.

Abelian group

In abstract algebra, an abelian group, also called a commutative group, is a group in which the result of applying the group operation to two group elements does not depend on the order in which they are written.
