    Zero sets of polynomials in several variables

  • Original language description

    Let k, n .. N, where n is odd. We show that there is an integer N = N(k,n) such that for every n-homogeneous polynomial P : RN .. R there exists a linear subspace X .. RN, dim X = k, such that P|x .IDENT. 0. This quantitative estimate improves on previous work of Birch et al., who studied this problem from an algebraic viewpoint. The topological method of proof presented here also allows us to obtain a partial solution to the Gromov-Milman problem (in dimension two) on an isometric version of a theoremof Dvoretzky.

    Nulové množiny polynomu několika proměnných

  • Czech description

    Pro zadaná přirozená čísla k,n, kde n je liché, ukážeme existenci čísla N = N(k,n) s následující vlastností. Pro každý n-homogenní polynom zadaný na Euklidovském prostoru dimenze N, existuje k-dimenzionální lineární podprostor, na němž se polynom anuluje.
