Riemannian Polyhedra and Liouville-type Theorems for Harmonic maps [PDF]

Analysis and Geometry in Metric Spaces, 2014
This paper is a study of harmonic maps from Riemannian polyhedra to (locally) non-positively curved geodesic spaces in the sense of Alexandrov. We prove Liouville-type theorems for subharmonic functions and harmonic maps under two different assumptions ...

A Liouville type theorem for p-Laplace equations

Electronic Journal of Differential Equations, 2015
In this note we study solutions defined on the whole space R^N for the p-Laplace equation $$ \hbox{div}(| \nabla u|^{p-2}\nabla u)+f(u)=0. $$ Under an appropriate condition on the growth of f, which is weaker than conditions previously considered ...

Existence Results for Fractional Differential Equations Under Weak Topology Features

Pan-American Journal of Mathematics, 2022
Using Krasnoselskii type fixed point theorem under the weak topology, we establish some sufficient conditions to ensure the existence of the weak solutions for kinds of initial value problems of fractional differential equations, involving Riemann ...

Uniqueness and Liouville type results for radial solutions of some classes of k-Hessian equations

Electronic Journal of Qualitative Theory of Differential Equations, 2022
We establish a uniqueness theorem and a Liouville type result for positive radial solutions of some classes of nonlinear autonomous equation with the $k$-Hessian operator. We also give some interesting qualitative properties of solutions.

Existence, stability and global attractivity results for nonlinear Riemann-Liouville fractional differential equations

Cubo, 2023
Existence, attractivity, and stability of solutions of a non-linear fractional differential equation of Riemann-Liouville type are proved using the classical Schauder fixed point theorem and a fixed point result due to Dhage.

Liouville type theorems for stationary Navier–Stokes equations [PDF]

SN Partial Differential Equations and Applications, 2021
We show that any smooth stationary solution of the 3D incompressible Navier-Stokes equations in the whole space, the half space, or a periodic slab must vanish under the condition that for some $0 \le \le ...

Wintner-type nonoscillation theorems for conformable linear Sturm-Liouville differential equations [PDF]

Opuscula Mathematica
In this study, we addressed the nonoscillation of th Sturm-Liouville differential equation with a differential operator, which corresponds to a proportional-derivative controller. The equation is a conformable linear differential equation. A Wintner-type
