โœฆ Synopsis


The geometry of an eigenvalue problem associated with the classical Dirichlet problem is illustrated using constructive geometric techniques. Based on a result of Guggenheimer, a geometric optimization problem defined over a convex domain is formulated and solved, and provides a measure of deviation of the domain from circular shape. An extension of the formulation is suggested and illustrated through example.

A method is proposed which allows the scattering problem to reduce to the eigenvalue problem. Unlike the usual method when the scattering phase is extracted from the asymptotits of solution of the Cauchy problem at a given collision energy, in the proposed method the collision energy is obtained fro
