Complete Solution of Hadamard's Problem for the Scalar Wave Equation on Petrov type III Space-Times
S. R. Czapor, R. G. McLenaghan, F. D. Sasse
We prove that there are no Petrov type III space-times on which the conformally invariant (self-adjoint) scalar wave equation or the non-self-adjoint scalar wave equation satisfies…

Huygens' Principle for the Non-Self-Adjoint Scalar Wave Equation on Petrov type III Space-Times
W. G. Anderson, R. G. McLenaghan, F. D. Sasse
We prove that if the non-self-adjoint scalar wave equation satisfies Huygens' principle on Petrov type III space-times, then it is equivalent to the conformally invariant scalar wa…
