Abstract
We obtain a polynomial upper bound in the finite-field version of the multidimensional polynomial Szemerédi theorem for distinct-degree polynomials. That is, if P1, …, Pt are nonconstant integer polynomials of distinct degrees and v1, …, vt are nonzero vectors in \(\mathbb{F}_p^D\), we show that each subset of \(\mathbb{F}_p^D\) lacking a nontrivial configuration of the form
has at most O(pD−c) elements. In doing so, we apply the notion of Gowers norms along a vector adapted from ergodic theory, which extends the classical concept of Gowers norms on finite abelian groups.
