In this talk I will present a proof of the Grothendieck-Riemann-Roch theorem as a special case of the family version of the Atiyah-Singer index theorem. In more details, we first give a Chern-Weil ...
WebThe key for Theorem 3.11 below is Lemma 2.4.2 of Leroy [18], recalled here for convenience. Leroy uses Lemma 3.10 together with Lemma 2.11 to show that for a locally connected Grothendieck topos E, the full subcategory Eslc of sums of locally constant objects is an atomic Grothendieck topos, cf.

WebDec 23, 2024 · In other words, \langle\cdot,\cdot\rangle, as a function of two variables, is an element of the projective tensor product C (B) {\displaystyle\hat {\otimes}} C (B). Its projective tensor norm is known as Grothendieck’s constant. The precise value of this constant is different in the real and complex case, and neither one is known exactly.
WebBy a nice result of Grothendieck we know that sheaf cohomology vanishes above the dimension of the variety [2, theorem III.2.7]. Hence in the case of a curve there is only a H0 and a H1. We then define the Euler characteristic (6) ˜(C,F):=h0(C,F) h1(C,F).
