We study matrices with real coefficients as transformations on the d-dimensional torus. We are interested in the size of the shrinking target sets, i.e., the sets of the points whose orbits under a fixed matrix transformation fall into a family of shrinking subsets infinitely often. We prove a zero-one law for the Lebesgue measure of such sets. We also give a Hausdorff dimension formula for the diagonal matrix transformations. This is a joint work with Bing Li, Sanju Velani and Evgeniy Zorin.
