If you have a question about this talk, please contact INI IT. This talk has been canceled/deleted We equate various Euler classes of algebraic vector bundles, including those of Barge—Morel, Kass—W., Déglise—Jin—Khan, and one suggested by M.J. Hopkins, A. Raksit, and J.-P. Serre. We establish integrality results for this Euler class, and give formulas for local indices at isolated zeros, both in terms of 6-functor formalism of coherent sheaves and as an explicit recipe in commutative algebra of Scheja and Storch. As an application, we compute the Euler classes associated to arithmetic counts of d-planes on complete intersections in P^n in terms of topological Euler numbers over R and C.
