11·î30Æü(ÌÚ) 13:30 -- 14:30 Victor Isakov(Wichita State Univ. USA) ``On the inverse diffusion problem'' ¡ãAbstarct of Prof.Isakov¡ä We consider identification of the diffusion coefficient from many lateral boundary measurements. We give sharp (logarithmic) stability estimates and numerical results in the one-dimensional case and uniqueness and stability for the linerization of this problem in the two-dimensional case.
