A variational principle and its application to estimating the electrical capacitance of a perfect conductor

Alexander G. Ramm

Published 2014-02-13Version 1

Assume that A is a bounded selfadjoint operator in a Hilbert space H. Then, the variational principle is obtained for some functional. As an application of this principle, a variational principle for the electrical capacitance of a conductor of an arbitrary shape is derived.
