Nontrivial Solutions of the Kirchhoff-Type Fractional p-Laplacian Dirichlet Problem

open access: yesJournal of Function Spaces, 2020
In this article, we consider the new results for the Kirchhoff-type p-Laplacian Dirichlet problem containing the Riemann-Liouville fractional derivative operators.

A Direct Approach for Detection of Bottom Topography in Shallow Water

open access: yesStudies in Applied Mathematics, Volume 157, Issue 2, August 2026.
ABSTRACT We propose a fast, stable, and direct analytic method to detect underwater channel topography from surface wave measurements, based on one‐dimensional shallow water equations. The technique requires knowledge of the free surface and its first two time derivatives at a single instant t★$t^{\star }$ above the fixed, bounded open segment of the ...

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

open access: yesStatistica 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.

A Liouville-type theorem for 3D stationary Navier–Stokes equations

open access: yesResults in Applied Mathematics
In this paper, we establish a Liouville-type theorem for smooth solutions of the stationary Navier–Stokes equations under a growth condition on the Lebesgue norms. Based on this condition, we prove a lemma analogous to the Poincaré-type inequality in the

A Liouville type theorem for Lane–Emden systems involving the fractional Laplacian [PDF]

open access: yes, 2015
We establish a Liouville type theorem for the fractional Lane–Emden system: {(−Δ)αu=vqin  RN,(−Δ)αv=upin  RN, where α∈(0,1), 2\alpha $ ?>N>2α and p, q are positive real numbers and in an appropriate new range.

Kazdan–Warner obstructions for a fourth‐order boundary problem

open access: yesBulletin 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.

Weinstein neighborhood theorems for stratified subspaces

open access: yesJournal 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.

A Survey of Nonlinear Sturm-Liouville Equations [PDF]

open access: yes, 2013
[[abstract]]This note gives a brief survey of existence, uniqueness and bifurcation results for nonlinear Sturm-Liouville equations. Early in 1960, Nehari made an interesting proposal to study solutions with a prescribed number of nodes.

A Liouville theorem of VT-harmonic map heat flow [PDF]

open access: yes, 2023
We proved an Liouville theorem for Backward V T-harmonic map heat flow from evolution manifolds into generalized regular ball. Among others, we also proved an Liouville theorem for V T-harmonic map heat flow from complete manifolds into generalized ...
