Massive Spanning Forests on the Complete Graph: Exact Distribution and Local Limit

Random Structures &Algorithms, Volume 68, Issue 2, March 2026.
ABSTRACT We provide new exact formulas for the distribution of massive spanning forests on the complete graph, which give also a new outlook on the celebrated special case of the uniform spanning tree. As a corollary we identify their local limit. This generalizes a well‐known theorem of Grimmett on the local limit of uniform spanning trees on the ...

Multiple Solutions for a Class of -Laplacian Systems

Journal of Inequalities and Applications, 2009
We study the multiplicity of solutions for a class of Hamiltonian systems with the -Laplacian. Under suitable assumptions, we obtain a sequence of solutions associated with a sequence of positive energies going toward infinity.

Depth Completion with Anisotropic Metric, Convolutional Stages, and Infinity Laplacian

Applied Sciences
Depth map estimation is crucial for a wide range of applications. Unfortunately, it often presents missing or unreliable data. The objective of depth completion is to fill in the “holes” in a depth map by propagating the depth information using guidance ...

A Generalization Error Bound of Physics‐Informed Neural Networks for Ecological Diffusion Models

Stat, Volume 15, Issue 1, March 2026.
ABSTRACT Ecological diffusion equations (EDEs) are partial differential equations (PDEs) that model spatiotemporal dynamics, often applied to wildlife diseases. Derived from ecological mechanisms, EDEs are useful for forecasting, inference, and decision‐making, such as guiding surveillance strategies for wildlife diseases.

Asymmetric Robin boundary-value problems with p-Laplacian and indefinite potential

Electronic Journal of Differential Equations, 2018
Four nontrivial smooth solutions to a Robin boundary-value problem with p-Laplacian, indefinite potential, and asymmetric nonlinearity super-linear at infinity are obtained, all with sign information.

Three‐Dimensional Forward Modeling of Vector and Tensor Gravitational Fields Using the FFT‐Accelerated Finite‐Difference Scheme

Earth and Space Science, Volume 13, Issue 3, March 2026.
Abstract Three‐dimensional gravity forward modeling with conventional numerical methods requires solving large‐scale linear system using direct matrix inversion or iterative solvers, incurring substantial computational costs that critically limit large‐scale three‐dimensional inversions.

Existence and multiplicity of solutions for nonlinear equations involving the square root of the Laplacian

Electronic Journal of Differential Equations, 2017
This paper deals with the existence and multiplicity results for fractional problem involving the square root of the Laplacian $A_{1/2}$ in a bounded domain with zero Dirichlet boundary conditions by Morse theory and critical groups for a $C^{1 ...

The Infinity Laplacian Eigenvalue Problem: Reformulation and a Numerical Scheme

Journal of Scientific Computing
AbstractIn this work, we present an alternative formulation of the higher eigenvalue problem associated to the infinity Laplacian, which opens the door for numerical approximation of eigenfunctions. A rigorous analysis is performed to show the equivalence of the new formulation to the traditional one.

A Thermodynamic Framework for Turing‐Type Instabilities in Porous Media: Part I Theory

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract Pattern formation in geological materials is commonly described using analogies to Turing‐type reaction–diffusion systems, yet a unifying thermodynamic explanation remains elusive. Here we develop a multiscale, thermodynamically consistent framework for pattern‐forming instabilities in porous media undergoing coupled thermo–hydro–mechanical ...
