Query: On a two-dimensional analog of Szemeredi's Theorem in Abelian groups   Let G be a finite Abelian group and A be a subset G\times G of cardinality at
least |G|^2/(log log |G|)^c, where c>0 is an absolute constant. We prove that A
contains a triple {(k,m), (k+d,m), (k,m+d)}, where d does not equal 0. This
theorem is a two-dimensional generalization of Szemeredi's theorem on
arithmetic progressions.
