Abstract: Let A and B be compact sets in mathbbRd. One of the fundamental problems in Geometric Measure Theory is to study the relations between the Hausdorff dimensions of A, B, and Acapf(B), where f runs through a set of transformations. Many mathematicians have studied this type of question intensively, including Bishop, Elekes, Falconer, Mattila, Kahane, Keleti, Peres.... In this talk, I discuss recent results on the discrete analog of this topic. Our approach is based on a number of techniques including algebraic methods and discrete Fourier Analysis. This is joint work with Semin
Yoo (KIAS, Korea).
