Uniqueness of positive solutions for cooperative Hamiltonian elliptic systems

open access: yesElectronic Journal of Differential Equations, 2016
The uniqueness of positive solution of a semilinear cooperative Hamiltonian elliptic system with two equations is proved for the case of sublinear and superlinear nonlinearities. Implicit function theorem, bifurcation theory, and ordinary differential

Recent Advances in Numerical Methods for Stochastic Differential Equations: From Classical Schemes to Wavelet‐Based Techniques

open access: yesJournal of Applied Mathematics, Volume 2026, Issue 1, 2026.
Stochastic processes prevail throughout fields as diverse as finance, physics, and biology, demanding increasingly sophisticated mathematical tools. These are the principal components of modeling systems influenced by random forces. The present work offers a structured examination of the solution landscape, progressing from foundational classical ...

Semilinear elliptic problems involving Hardy-Sobolev-Maz'ya potential and Hardy-Sobolev critical exponents

open access: yesElectronic Journal of Differential Equations, 2016
In this article, we study a class of semilinear elliptic equations involving Hardy-Sobolev critical exponents and Hardy-Sobolev-Maz'ya potential in a bounded domain. We obtain the existence of positive solutions using the Mountain Pass Lemma.

Stability Analysis of Linear and Nonlinear Abstract Cauchy Problems With Resolvent Kernels Using a Novel Hybrid Fractional Derivative Approach

open access: yesJournal of Function Spaces, Volume 2026, Issue 1, 2026.
Consider an injective closed linear operator Λ defined on a Banach space Ψ and introduce the modified Atangana–Baleanu–Caputo (mABC) fractional derivative, denoted by mABCDtγ. We demonstrate the existence of a unique solution to the abstract Cauchy problem mABCDtγut=Mγ1/1−γ+χγft−Mγ/1−γEγ−χγtγft−MγχγΛut,t≥0.

Spectral properties of non-local uniformly-elliptic operators [PDF]

open access: yes, 2006
In this paper we consider the spectral properties of a class of non-local uniformly elliptic operators, which arise from the study of non-local uniformly elliptic partial differential equations. Such equations arise naturally in the study of a variety of

Six One‐Sign Solutions for Semilinear Elliptic Problems in ℝN*

open access: yesJournal of Function Spaces, Volume 2026, Issue 1, 2026.
In this work, we consider the existence of one‐sign solutions for semilinear elliptic problems: {−Δu = λa(x)f(u), in ℝN, u(x)⟶0, as|x|⟶+∞, where N ≥ 3, λ is a real parameter and a ∈ C(ℝN, ℝ) is a weighted function, f ∈ C(ℝ, ℝ). Furthermore, by bifurcation technique, we identify the interval of bifurcation parameter in which the semilinear elliptic ...

Some properties of Palais-Smale sequences with applications to elliptic boundary-value problems

open access: yesElectronic Journal of Differential Equations, 1999
When using calculus of variations to study nonlinear elliptic boundary-value problems on unbounded domains, the Palais-Smale condition is not always satisfied.

Computation of radial solutions of semilinear equations

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2007
We express radial solutions of semilinear elliptic equations on $R^n$ as convergent power series in $r$, and then use Pade approximants to compute both ground state solutions, and solutions to Dirichlet problem.
