报告题目：Sharp bounds of eigenvalues and related inverse problems for differential operators

报告简介：We develop an analytical method to prove the sharp upper and lower bounds for eigenvalue of ordinary differential operators. In particular, we focus on the indefinite potentials. We also study a kind of inverse spectral problems, which means that the optimal lower bounds of norms of the potentials can be obtained when eigenvalue and the average of the potentials are fixed. We use the setting of measure differential equations to understand the direct spectral problems as well as the inverse problems because the solutions for them will lead to Dirac measure distributions of potentials.
