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…
Nonexistence of Petrov type III Space-Times on which Weyl's Neutrino Equation or Maxwell's Equations satisfy Huygens' Principle
R. G. McLenaghan, F. D. Sasse
Extending previous results we show that there are no Petrov type III space-times on which either the Weyl neutrino equation or Maxwell's equations satisfy Huygens' principle. We pr…
Obtaining Membership Functions from a Neuron Fuzzy System extended by Kohonen Network
Angelo Luis Pagliosa, Claudio Cesar de Sa, Fernando D. Sasse
This article presents the Neo-Fuzzy-Neuron Modified by Kohonen Network (NFN-MK), an hybrid computational model that combines fuzzy system technique and artificial neural networks.…
