Commutative diagrams are graphical representations used in mathematics to illustrate the relationships between different objects and morphisms in a category. In the context of cohomology, these diagrams help visualize how various sequences of functions or maps behave under composition, ensuring that the paths taken through the diagram lead to the same result. They are particularly useful for representing long exact sequences in cohomology, showcasing how certain properties and relationships among spaces are preserved under these mappings.
