WebThe Kunneth formula induces a Hopf algebra structure on the étale cohomology H*(G; Z/€) of a reductive group G over k which does not depend on a passage to characteristic 0 theory, and hence avoids the classification of reductive group-schemes over arbitrary bases. It also leads to an alternate proof of a recent theorem of Friedlander stata create new variable with conditions

There are many generalized (or "extraordinary") homology and cohomology theories for topological spaces. K-theory and cobordism are the best-known. Unlike ordinary homology and cohomology, they typically cannot be defined using chain complexes. Thus Künneth theorems can not be obtained by the above … 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 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 by cellular homology, because that is … 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 • "Künneth formula", Encyclopedia of Mathematics, EMS Press, 2001 [1994] See more WebarXiv:math/0404051v2 [math.DG] 28 May 2009 AN EXPLICIT PROOF OF THE GENERALIZED GAUSS-BONNET FORMULA HENRI GILLET AND FATIH M.
