Existence of Positive Solutions for a Class of px,qx-Laplacian Elliptic Systems with Multiplication of Two Separate Functions

open access: yesComplexity, 2020
The paper deals with the study of the existence of weak positive solutions for a new class of the system of elliptic differential equations with respect to the symmetry conditions and the right hand side which has been defined as multiplication of two ...

Adaptation and fatigue model for neuron networks and large time asymptotics in a nonlinear fragmentation equation. [PDF]

open access: yesJ Math Neurosci, 2014
Motivated by a model for neural networks with adaptation and fatigue, we study a conservative fragmentation equation that describes the density probability of neurons with an elapsed time s after its last discharge.

On global existence for semilinear wave equations with space-dependent critical damping [PDF]

open access: yesJournal of the Mathematical Society of Japan, 2021
The global existence for semilinear wave equations with space-dependent critical damping ∂ t u−∆u+ V0 |x| ∂tu = f(u) in an exterior domain is dealt with, where f(u) = |u|p−1u and f(u) = |u| are in mind.

Coupled and uncoupled sign-changing spikes of singularly perturbed elliptic systems [PDF]

open access: yesCommunications in Contemporary Mathematics, 2021
We study the existence and asymptotic behavior of solutions having positive and sign-changing components to the singularly perturbed system of elliptic equations in a bounded domain Ω in R N , with N ≥ 4, ε > 0, µ i > 0, λ ij = λ ji < 0, α ij , β ij > 1,

Asymptotic stability analysis of Riemann-Liouville fractional stochastic neutral differential equations [PDF]

open access: yesMiskolc Mathematical Notes, 2021
The novelty of our paper is to establish results on asymptotic stability of mild solutions in pth moment to Riemann-Liouville fractional stochastic neutral differential equations (for short Riemann-Liouville FSNDEs) of order α ∈ ( 2 ,1) using a Banach’s ...

On the asymptotic behavior of a size-structured model arising in population dynamics

open access: yesMalaya Journal of Matematik, 2023
We study the asymptotic behavior of a semilinear size-structured population model withdelay when the nonlinearity is small in some sense. The novelty in this work is that theoperator governing the linear part of the equation does not generate a compact ...

Global Limit Theorem for Parabolic Equations with a Potential [PDF]

open access: yesSIAM Journal on Mathematical Analysis, 2021
We obtain the asymptotics, as t + |x| → ∞, of the fundamental solution to the heat equation with a compactly supported potential. It is assumed that the corresponding stationary operator has at least one positive eigenvalue.

General decay rate for a viscoelastic wave equation with distributed delay and Balakrishnan-Taylor damping

open access: yesOpen Mathematics, 2021
A nonlinear viscoelastic wave equation with Balakrishnan-Taylor damping and distributed delay is studied. By the energy method we establish the general decay rate under suitable hypothesis.

The evolution to equilibrium of solutions to nonlinear Fokker-Planck equation [PDF]

open access: yesIndiana University Mathematics Journal, 2019
One proves the $H$-theorem for mild solutions to a nondegenerate, nonlinear Fokker-Planck equation $$ u_t-\Delta\beta(u)+\mathrm{ div}(D(x)b(u)u)=0, \ t\ge0, \ x\in\mathbb{R}^d,\hspace{1cm} (1)$$ and under appropriate hypotheses on $\beta,$ $D$ and $b ...
