The associated eigenvalue problem, which has been recently found to yield complex roots that were not accounted for within most previous works, is accurately and automatically treated through the generalized integral transform technique (GITT). This approach allows for a definitive establishment of the eigenvalues spectra, including any number of complex eigenvalues, which appear for certain combinations of the governing parameters in the partial differential formulation. Representative examples are selected and the convergence characteristics of the exact solution are illustrated. %8 1999-12-01
