Inhomogeneous Diophantine Approximation on M_0 sets.
Abstract: We formulate and prove a Khintchine-type law on inhomogeneous Diophantine approximation, where the denominators lie in certain subsets of the positive integers. The size of the corresponding set of well approximable numbers is given by a probability measure with sufficiently fast decaying Fourier coefficients.
