Inverse Probleme der Potentialtheorief

摘要

For the volume potential u(x) = (4#x3C0;)-1#x222B;GX-y-1#x3BC;(y) dy the problems of (a) finding ju for given #x2A3F;u and G and (b) finding G for given and #x2A3F;arc considered, in case (a) the kernel and in case (b) the Frechet derivative of the related integral operators arc investigated so that the approximation procedures of A. N. Tikhonov can be applied.
