Liouville type theorems for the stationary Hall-MHD equations in local Morrey spaces

, 2022
This paper is concerned with the Liouville type theorems for the 3D stationary incompressible Hall-MHD equations. We establish that under some sufficient conditions in local Morrey spaces, solutions of the stationary Hall-MHD equations are identically ...

A sequential quadratic Hamiltonian‐based estimation method for Box‐Cox transformation cure model

Statistica Neerlandica, Volume 80, Issue 3, August 2026.
ABSTRACT We propose an enhanced estimation method for the Box‐Cox transformation (BCT) cure rate model parameters by introducing a generic maximum likelihood estimation algorithm, the sequential quadratic Hamiltonian (SQH) scheme, which is based on a gradient‐free approach.

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

Kazdan–Warner obstructions for a fourth‐order boundary problem

Bulletin of the London Mathematical Society, Volume 58, Issue 8, August 2026.
Abstract We derive Kazdan–Warner type identities for the boundary problem of prescribing nonconstant interior Q$Q$ curvature and boundary T$T$ curvature on the upper hemisphere S+4${\mathbb {S}}^{4}_{+}$ by a conformal change of the standard metric.

Liouville type theorems for φ-subharmonic functions

, 2001
In this paper we presents some Liouville type theorems for solutions of differential inequalities involving the φ-Laplacian. Our results, in particular, improve and generalize known results for the Laplacian and the p-Laplacian, and are new even in these

On Liouville's theorem and the Strong Liouville Property

This new version refines the previous version of the paper titled "On Liouville's theorem". A section has been added where a Liouville-type theorem is shown for the p-Laplacian on a Riemannian surface with a pole with $p\ge 2$ under a curvature condition. The title has changed.

Weinstein neighborhood theorems for stratified subspaces

Journal of the London Mathematical Society, Volume 114, Issue 2, August 2026.
Abstract By analogy with Weinstein's neighborhood theorem, we prove a uniqueness result for symplectic neighborhoods of a large family of stratified subspaces. This result generalizes existing constructions, for example, in the search for exotic Lagrangians.

On ( p , q ) $(p,q)$ -classical orthogonal polynomials and their characterization theorems

Advances in Difference Equations, 2017
In this paper, we introduce a general ( p , q ) $(p, q)$ -Sturm-Liouville difference equation whose solutions are ( p , q ) $(p, q)$ -analogues of classical orthogonal polynomials leading to Jacobi, Laguerre, and Hermite polynomials as ( p , q ) → ( 1 ...

A stochastic approach to a priori estimates and Liouville theorems for harmonic maps [PDF]

, 2011
peer reviewedNonlinear versions of Bismut type formulas for the differential of a harmonic map between Riemannian manifolds are used to establish a priori estimates for harmonic maps. A variety of Liouville type theorems is shown to follow as corollaries
