题目：Dimension of Diophantine approximation, orthogonal projection and sum-product

报告人：刘博辰 （南方科技大学）

摘要：Given 0<s<1, we construct a new family of sets in the line of Hausdorff dimension s via Diophantine approximation, in which the classical Jarnik example is the endpoint case. Then we are able to show a recent result of Ren and Wang, known sharp on orthogonal projection, is also  sharp on A+cB, c\in C. This is joint work with Longhui Li.
