An extermal problem in finite geometry

Abstract:

For a given restriction $H$ of PG$(m-1,q)$ and any $n>m$, we consider the maximum number of points in PG$(n-1,q)$ not containing a copy of $H$. We prove a striking analogue of the Erdös-Stone Theorem. The proof is surprisingly easy, but relies on a very deep result related to the density version of the multidimensional Hales-Jewett theorem.

This is joint work with Peter Nelson.
