1. Generalized cohomology theories: extraordinary cohomology theories A class of special functors from the category of pairs of spaces into the category of graded Abelian groups. A generalized cohomology theory is a pair $ ( h ^ {*} , \delta ) $, where $ h ^ {*} $ is a functor from the category $ P ... (Mathematics) [100%] 2023-06-24

1. Cohomology: A term used with respect to functors of a homological nature that, in contrast to homology, depend contravariantly, as a rule, on the objects of the basic category on which they are defined. In contrast to homology, connecting homomorphisms in ... (Mathematics) [97%] 2023-10-20
2. Cohomology: In category theory, the cohomology of an exact sequence studies the relationship between the cokernels and coimages, when it is possible to take their quotient. Cohomology is the category-theoretic dual of homology. [97%] 2023-02-18

Cohomology: In mathematics, specifically in homology theory and algebraic topology, cohomology is a general term for a sequence of abelian groups, usually one associated with a topological space, often defined from a cochain complex.
