内容摘要:本报告将介绍利用一族第一特征值(类谱函数)唯一恢复谱问题中未知势函数的方法。这与经典的逆谱理论利用两族谱(或等价的谱数据)唯一恢复势函数的方法不同,其优点在于第一特征值是易于获取的谱数据。报告将介绍类谱函数的各种性质,研究类谱函数恢复未知势函数的存在性、唯一性、稳定性和重构四大问题,同时也提出相应的最优恢复问题。
报告人简介:Jiangang Qi is a professor of Mathematics at the School of Mathematics and Statistics, Shandong University at Weihai. He received the M.E. degree in Mathematics from Shandong Normal University in 1988 and the Ph.D. degree from Mathematics from Shandong University in 2002. His researcheffortconcentrates onboundary valueproblems and the spectral theories ofdifferential operators.
