Einige Bemerkungen über den Satz von Keldych.
Let be an open set with a compact boundary and let be a finite measure on . Consider the space of all -integrable functions on and, for each...
A new and elegant procedure is proposed for the solution of mixed potential problems in a half-space with a circular line of division of boundary conditions. The approach is based on a new type of integral operators with special properties. Two general external problems are solved; i) An arbitrary potential is specified at the boundary outside a circle, and its normal derivative is zero inside; ii) An arbitrary normal derivative is given outside the circle, and be potential is zero inside. Several...
