On the distribution of S-integral lattice points under isotropic quadratic forms:  The Oppenheim conjecture and related problems are one of the historical topics in homogeneous dynamics and its application to number theory. In this talk, I briefly review which kind of problems are studied in this area and talk about their generalization to the S-arithmetic space.
