In category theory, equivalence of categories is a fundamental concept that captures the idea of two categories being "essentially the same" in a categorical sense. Two categories \\( \\mathcal\{C\} \\) and \\( \\mathcal\{D\} \\) are said to be equivalent if there exists a pair of functors between them that reflect a correspondence of their structural features, without necessarily being isomorphic.
