The Sturm-Liouville solutions of the 3D-wave equation when the refractive index depends only on the radial variable r are deduced from solutions of the 1D-wave equation that the Laplace and Fourier transforms change into a Sturm-Liouville equation. 关键词: BENZENE IONIZATION MASS SPECTROSCOPY ZEKE...
This short paper derives the constant of motion of a scalar field in the gravitational field of a Kerr black hole which is associated to a Killing tensor of that space-time. In addition, there is found a related new symmetry operator S for the solutions of the wave equation in that back...

The paper studies the blowup of solutions to the initial boundary value problem for the "bad" Boussinesq-type equation utt−uxx−buxxxx=σ(u)xx, where b>0 is a real number and σ(s) is a given nonlinear function. By virtue of the energy method and the Fourier transform method, res...
