摘要

The generalized integral transform technique (GITT) is employed in obtaining formal solutions for eigenvalue problems of the Sturm-Liouville type, described by multi-dimensional partial differential models within irregularly shaped domains. The successive elimination of independent variables in the appropriate order through integral transformations produces the associated algebraic eigenvalue problem, which is then readily solved by algorithms from scientific subroutine libraries. A representative example of the known exact solution is presented, of particular interest to the field of heat and mass diffusion, for validation purposes. [References: 20]
