Abstract
We prove inverse theorems for the size of sumsets and the L
q norms of
convolutions in the discretized setting, extending to arbitrary dimension an earlier
result of the author in the line. These results have applications to the dimensions
of dynamical self-similar sets and measures, and to the higher dimensional fractal
uncertainty principle. The proofs are based on a structure theorem for the entropy of
convolution powers due to M. Hochman.
