Query: Szemeredi-type theorems for subsets of locally compact abelian groups of
  positive upper Banach density   By using ergodic theoretic techniques following Hillel F\"{u}rstenberg, we
prove that measurable subsets of a locally compact abelian group of positive
upper density contain Szemer\'{e}di-wise configurations defined by an arbitrary
compact subset of the group.
