External Ellipsoidal Harmonics for the Dunkl-Laplacian
arXiv:0812.4365 · doi:10.3842/SIGMA.2008.091
Abstract
The paper introduces external ellipsoidal and external sphero-conal -harmonics for the Dunkl-Laplacian. These external -harmonics admit integral representations, and they are connected by a formula of Niven's type. External -harmonics in the plane are expressed in terms of Jacobi polynomials and Jacobi's functions of the second kind.
