A Künneth Formula for Finite Sets SpringerLink

A Künneth theorem or Künneth formula is true in many different homology and cohomology theories, and the name has become generic. These many results are named for the German mathematician Hermann Künneth . Singular homology with coefficients in a field [ edit] Let X and Y be two topological spaces. See more In mathematics, especially in homological algebra and algebraic topology, a Künneth theorem, also called a Künneth formula, is a statement relating the homology of two objects to the homology of their product. The classical … See more For a general commutative ring R, the homology of X and Y is related to the homology of their product by a Künneth spectral sequence See more The chain complex of the space X × Y is related to the chain complexes of X and Y by a natural quasi-isomorphism For singular chains … See more • "Künneth formula", Encyclopedia of Mathematics, EMS Press, 2001 [1994] See more Let X and Y be two topological spaces. In general one uses singular homology; but if X and Y happen to be CW complexes, then this can be replaced … See more The above formula is simple because vector spaces over a field have very restricted behavior. As the coefficient ring becomes more general, the relationship becomes more complicated. The next simplest case is the case when the coefficient ring is a See more There are many generalized (or "extraordinary") homology and cohomology theories for topological spaces. K-theory and cobordism are the best-known. Unlike ordinary homology … See more WebFor example in KO-theory the map a is not always injective.$ Thus for a Kneth formula to hold one has to assume some additional special property of the theory.
