报告题目：Convergence Rates of Tikhonov Regularizations forElliptic and Parabolic Inverse Radiativity Problems

地点：杏林楼A区207

报告摘要：In thistalk, we shall study the convergence rates of the Tikhonov regularized solutions for the recovery of the radiativities in elliptic and parabolicsystems in general dimensional spaces. The conditional stability estimates arefirst derived. Due to the difficulty of the verification of the existing sourceconditions or nonlinearity conditions of the inverse radiativity problems inhigh dimensional spaces, some new variational source conditions are proposed. The conditions are rigorously verified in general dimensional spacesunder the conditional stability estimates. We will also derive the reasonableconvergence rates under the new source conditions, and the results reveal theexplicit relation between the regularity of the radiativities and the convergencerates.
