报告摘要:In this talk, we will discuss some recent progress on numerical algorithms for inverse spectral problem based upon trace formulas for some typical differential operators. Instead of inverting the map from spectral to coefficients directly, we propose a novel method to reconstruct the coefficients based on inverting a sequence of trace formulas which bridge the spectral and geometry information clearly in terms of a series of nonlinear Fredholm integral equations. Numerical experiments are presented to verify the validity and effectiveness of the proposed numerical algorithm. The impact of different parameters involved in the algorithm is also discussed.
