Abstract

A weighted $p$-Laplacian parabolic equation is studied and applied to achieve $(p, \alpha, \beta)$-spectrum and decomposition of a signal. Weak solutions to the equation are existent by the Faedo–Galerkin method. $(p, \alpha, \beta)$-spectrum and decomposition are acquired by means of eigenfunctions of $\Delta_{p,\alpha}$ and fractional order derivatives.

Keywords

weighted $p$-Laplace, $(p, \alpha, \beta)$-spectrum, signal decomposition
