Anisotropic Picone identities and anisotropic Hardy inequalities. [PDF]

J Inequal Appl, 2017
In this paper, we derive an anisotropic Picone identity for the anisotropic Laplacian, which contains some known Picone identities. As applications, a Sturmian comparison principle to the anisotropic elliptic equation and an anisotropic Hardy type ...

A generalized nonlinear Picone identity for the p-biharmonic operator and its applications

Journal of Inequalities and Applications, 2019
A generalized nonlinear Picone identity for the p-biharmonic operator is established in this paper. As applications, a Sturmian comparison principle to the p-biharmonic equation with singular term, a Liouville’s theorem to the p-biharmonic system, and a ...

Rayleigh principle for time scale symplectic systems and applications

Electronic Journal of Qualitative Theory of Differential Equations, 2011
In this paper we establish the Rayleigh principle, i.e., the variational characterization of the eigenvalues, for a general eigenvalue problem consisting of a time scale symplectic system and the Dirichlet boundary conditions.

Generalized Picone's identity and its applications

Electronic Journal of Differential Equations, 2013
In this article we give a generalized version of Picone's identity in a nonlinear setting for the p-Laplace operator. As applications we give a Sturmian Comparison principle and a Liouville type theorem.
