Grothendieck cycle
In mathematics, the standard conjectures about algebraic cycles are several conjectures describing the relationship of algebraic cycles and Weil cohomology theories. One of the original applications of these conjectures, envisaged by Alexander Grothendieck, was to prove that his construction of pure motives gave an abelian category that is semisimple. Moreover, as he pointed out, the standard conjectures also imply the hardest part of the Weil conjectures, namely the "Riemann h… Webory of motives along the lines indicated by Grothendieck. We further quote recent developments, also presenting some advances due to Vo-evodsky, and applications to the study of algebraic cycles and differential forms.

WebJun 6, 2010 · Remarks on Grothendieck's standard conjectures. Alexander Beilinson. We show that Grothendieck's standard conjectures are implied by either of two other motivic conjectures: (a) by that of the existence of the motivic t-structure, and (b) by (a weak form of) Suslin's Lawson homology conjecture. Subjects: WebThen the Grothendieck-Riemann-Roch theorem states that for a 2K(X), ch(f a)td(T Y)= f (ch(a)td(T X)) in the ring H(Y;Q). The map f on cohomology can be described in the …

WebFeb 2, 2015 · So even if the cohomology was ready long before that, Grothendieck had to regard it as unsolved in 1968, when he wrote about the standard conjectures. It is also reasonable to imagine that he had hopes at those early stages for crystalline cohomology to be an important tool in the yoga of motives.

First, étale neighborhood are finer than Zariski one. Hence they are "closer" to the classical neighborhood. For example, the curve y 2 = x 3 + x 2 is irreducible and has a node at x = ( 0, 0).
