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 ...

Existence of solutions for a class of degenerate quasilinear elliptic equation in RN with vanishing potentials

open access: yesBoundary Value Problems, 2013
We establish the existence of positive solution for the following class of degenerate quasilinear elliptic problem (P){−Luap+V(x)|x|−ap∗|u|p−2u=f(u)in RN,u>0in RN;u∈Da1,p(RN), where −Luap=−div(|x|−ap|∇u|p−2∇u ...

Positive solution for a class of coupled (p,q)-Laplacian nonlinear systems

open access: yesBoundary Value Problems, 2014
In this article, we prove the existence of a nontrivial positive solution for the elliptic system {−Δpu=ω(x)f(v)in Ω,−Δqv=ρ(x)g(u)in Ω,(u,v)=(0,0)on ∂Ω, where Δp denotes the p-Laplacian operator, p,q>1 and Ω is a smooth bounded domain in RN (N≥2).

Existence and uniqueness of a positive solution to generalized nonlocal thermistor problems with fractional-order derivatives ∗ [PDF]

open access: yes, 2011
In this work we study a generalized nonlocal thermistor problem with fractional-order Riemann–Liouville derivative. Making use of fixed-point theory, we obtain existence and uniqueness of a positive solution.

Existence of non-constant positive stationary solutions of the shadow predator-prey systems with Allee effect

open access: yesAdvances in Differential Equations, 2014
In this paper, we consider the dynamics of the shadow system of a kind of homogeneous diffusive predator-prey system with a strong Allee effect in prey.

Criticality theory for Schrödinger operators on graphs

open access: yesJournal of Spectral Theory, 2017
We study Schrödinger operators given by positive quadratic forms on infinite graphs. From there, we develop a criticality theory for Schrödinger operators on general weighted graphs. Mathematics Subject Classification (2010).
