Liouville theorems for Kirchhoff-type parabolic equations and system on the Heisenberg group
In this article, the Liouville theorems for the Kirchhoff-type parabolic equations on the Heisenberg group were established. The main technique for proving the result relies on the method of test functions.

A C^1 Arnol'd-Liouville theorem
In this paper, we prove a version of Arnol'd-Liouville theorem for C 1 commuting Hamiltonians. We show that the Lipschitz regularity of the foliation by invariant Lagrangian tori is crucial to determine the Dynamics on each Lagrangian torus and that the C 1 regularity of the foliation by invariant Lagrangian tori is crucial to prove the continuity of ...

Liouville theorems and $1$-dimensional symmetry for solutions of an elliptic system modelling phase separation [PDF]
We consider solutions of the competitive elliptic system \[ \left\{ \begin{array}{ll} -\Delta u_i = - \sum_{j \neq i} u_i u_j^2 & \text{in $\mathbb{R}^N$} \\ u_i >0 & \text{in $\mathbb{R}^N$} \end{array}\right. \qquad i=1,\dots,k.

Improved Liouville theorems for axially symmetric Navier-Stokes equations [PDF]
In this paper, we consider the Liouville property for ancient solutions of the incompressible Navier-Stokes equations. In 2D and 3D axially-symmetric cases without swirl, we prove the sharp Liouville theorems for smooth ancient mild solutions: Velocity ...

A new kind of uniqueness theorems for inverse Sturm-Liouville problems

Extensions of a theorem of Cauchy–Liouville
AbstractWe deal with the equations Δpu+f(u)=0 and Δpu+(p−1)g(u)|∇u|p+f(u)=0 in RN, where g(t) is a continuous function in (0,∞), p>1 and f(t) is a smooth function for t>0. Under appropriate conditions on g and f we show that the corresponding equation cannot have nontrivial non-negative entire solutions.
