Killing–Yano tensors and variable separation in Kerr geometry
Kalnins, Ernie G.; Miller, W., Jr.; Williams, G.C. (198910)A complete analysis of the freefield massless spins equations (s=0, (1)/(2) ,1) in Kerr geometry is given. It is shown that in each case the separation constants occurring in the solutions obtained from a potential ... 
Matrix operator symmetries of the Dirac equation and separation of variables
Kalnins, Ernie G.; Miller, W., Jr.; Williams, G.C. (198607)The set of all matrixvalued firstorder differential operators that commute with the Dirac equation in ndimensional complex Euclidean space is computed. In four dimensions it is shown that all matrixvalued secondorder ... 
Superintegrability in threedimensional Euclidean space
Kalnins, Ernie G.; Williams, G.C.; Miller, W., Jr.; Pogosyan, G.S. (199902)Potentials for which the corresponding Schrödinger equation is maximally superintegrable in threedimensional Euclidean space are studied. The quadratic algebra which is associated with each of these potentials is constructed ... 
Symmetry operators and separation of variables for spinwave equations in oblate spheroidal coordinates
Kalnins, Ernie G.; Williams, G.C. (199007)A family of secondorder differential operators that characterize the solution of the massless spin s field equations, obtained via separation of variables in oblate spheroidal coordinates and using a null tetrad is found. ... 
Teukolsky–Starobinsky identities for arbitrary spin
Kalnins, Ernie G.; Miller, W., Jr.; Williams, G.C. (198912)The Teukolsky–Starobinsky identities are proven for arbitrary spin s. A pair of covariant equations are given that admit solutions in terms of Teukolsky functions for general s. The method of proof is shown to extend to ...
