Riemannian Polyhedra and Liouville-Type Theorems for Harmonic Maps [PDF]

open access: yesAnalysis and Geometry in Metric Spaces, 2014
AbstractThis paper is a study of harmonic maps fromRiemannian polyhedra to locally non-positively curvedgeodesic spaces in the sense of Alexandrov. We prove Liouville-type theorems for subharmonic functionsand harmonic maps under two different assumptions on the source space.

Indefinite Hamiltonian systems whose Titchmarsh–Weyl coefficients have no finite generalized poles of non-positive type [PDF]

open access: yes, 2013
The two-dimensional Hamiltonian system (*)  y'(x)=zJH(x)y(x),  x∈(a,b), where the Hamiltonian H takes non-negative 2x2-matrices as values, and $J:= \begin{pmatrix} 0 & -1 \\ 1 & 0 \end{pmatrix}$, has attracted a lot of interest over the past decades ...

A Contribution of Liouville-Type Theorems to the Geometry in the Large of Hadamard Manifolds

open access: yes, 2022
A complete, simply connected Riemannian manifold of nonpositive sectional curvature is called a Hadamard manifold. In this article, we prove Liouville-type theorems for isometric and harmonic self-diffeomorphisms of Hadamard manifolds, as well as ...

On Liouville-type theorems for the 2D stationary MHD equations

open access: yes, 2022
We establish new Liouville-type theorems for the two-dimensional stationary magneto-hydrodynamic incompressible system assuming that the velocity and magnetic field have bounded Dirichlet integral.

Liouville type theorems for anisotropic degenerate elliptic equations on strips

open access: yes, 2023
We establish ($L^\infty$) Liouville type theorems for anisotropic degenerate elliptic equations in divergence form on the strip $S=\R^{N-1}\times (-1,1)$ where $x=(x',\lambda)$. The model equation is $div_{x'} (w_1 \nabla_{x'}\sigma)+\partial_\lambda (

A Liouville-type Theorem on half-spaces for sub-Laplacians [PDF]

open access: yesProceedings of the American Mathematical Society, 2014
Summary: Let \( \mathcal {L}\) be a sub-Laplacian on \( \mathcal {L}^N\) and let \( \mathbb{G}=(\mathcal {L}^N,\circ ,\delta _\lambda )\) be its related homogeneous Lie group. Let \( \mathbb{E}\) be a Euclidean subgroup of \( \mathcal {L}^N\) such that the orthonormal projection \( \pi :\mathbb{G} \longrightarrow \mathbb{E}\) is a homomorphism of ...

A highly accurate numerical method for solving boundary value problem of generalized Bagley‐Torvik equation

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
A highly accurate numerical method is given for the solution of boundary value problem of generalized Bagley‐Torvik (BgT) equation with Caputo derivative of order 0<β<2$$ 0<\beta <2 $$ by using the collocation‐shooting method (C‐SM). The collocation solution is constructed in the space Sm+1(1)$$ {S}_{m+1}^{(1)} $$ as piecewise polynomials of degree at ...

A Liouville‐type theorem for cylindrical cones

open access: yesCommunications on Pure and Applied Mathematics
AbstractSuppose that is a smooth strictly minimizing and strictly stable minimal hypercone (such as the Simons cone), , and a complete embedded minimal hypersurface of lying to one side of . If the density at infinity of is less than twice the density of , then we show that , where is the Hardt–Simon foliation of .

Exponential Stability of Higher Order Fractional Neutral Stochastic Differential Equation Via Integral Contractors

open access: yesMathematical Methods in the Applied Sciences, Volume 48, Issue 6, Page 6425-6446, April 2025.
ABSTRACT The well‐posedness results for mild solutions to the fractional neutral stochastic differential system with Rosenblatt process with Hurst index Ĥ∈12,1$$ \hat{H}\in \left(\frac{1}{2},1\right) $$ is discussed in this article. To demonstrate the results, the concept of bounded integral contractors is combined with the stochastic result and ...
