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

An Inverse Spectral Problem for the Matrix Sturm-Liouville Operator with a Bessel-Type Singularity
International Journal of Differential Equations, 2015 The inverse problem by the Weyl matrix is studied for the matrix Sturm-Liouville equation on a finite interval with a Bessel-type singularity in the end of the interval.

A LIOUVILLE TYPE THEOREM FOR HARMONIC MORPHISMS
Journal of the Korean Mathematical Society, 2007 Let M be a complete Riemannian manifold and let N be a Riemannian manifold of nonpositive scalar curvature. Let μ0 be the least eigenvalue of the Laplacian acting on L2-functions on M . We show that if RicM ≥ −μ0 at all x ∈ M and either RicM > −μ0 at some point x0 or Vol(M) is infinite, then every harmonic morphism φ : M → N of finite energy is ...

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.

A Liouville-type theorem for 3D stationary Navier–Stokes equations
Results in Applied MathematicsIn 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

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.

On a Liouville-type theorem for the Ginzburg–Landau system
Comptes Rendus. Mathématique, 2017 We prove that entire, complex valued solutions to the Ginzburg–Landau system with positive real and imaginary parts are constant in any spatial dimension. This property was shown very recently only in the planar case.

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.
