            ``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.
