Abstract

Let GG be a locally compact group. We examine the problem of determining when nonzero functions in L2(G)L^2(G) have linearly independent translations. In particular, we establish some results for the case when GG has an irreducible, square integrable, unitary representation. We apply these results to the special cases of the affine group, the shearlet group and the Weyl-Heisenberg group. We also investigate the case when GG has an abelian, closed subgroup of finite index.
