The Generalized D'Alembert Operator on Compactified Pseudo-Euclidean Space
A. S. Blagoveshchenskii Saint-Petersburg State University
Abstract:
It is proved that the D'Alembert operator in R n with multidimensional time, bordered by operators of multiplication by some function, and subject to an acceptance condition at infinity is a self-adjoint operator with discrete spectrum. The spectrum and eigenfunctions are explicitly described.
Keywords:
D'Alembert differential operator, self-adjoint operator, pseudo-Euclidean space, conformal transformation group, Kelvin transformation, Laplace operator, spherical function.
