报告题目: Gaps between values of functions at integer points

报告摘要：Kleinbock and Weiss proved that for a set of binary quadratic forms Q with full Hausdorff dimension, the values of Q at nonzero integer points have gaps at a given countable set of real numbers. In this talk, we will discuss extensions of this result to functions of more variables. The proof will be based on investigations of nondense orbits of nonquasiunipotent homogeneous flows. This is an ongoing joint work with Lifan Guan and Dmitry Kleinbock.
