Sensitivity of the Solution to Nonsymmetric Differential Matrix Riccati Equation

open access: yes, 2021
Nonsymmetric differential matrix Riccati equations arise in many problems related to science and engineering. This work is focusing on the sensitivity of the solution to perturbations in the matrix coefficients and the initial condition.

On Bending of Bernoulli-Euler Nanobeams for Nonlocal Composite Materials

open access: yesModelling and Simulation in Engineering, 2016
Evaluation of size effects in functionally graded elastic nanobeams is carried out by making recourse to the nonlocal continuum mechanics. The Bernoulli-Euler kinematic assumption and the Eringen nonlocal constitutive law are assumed in the formulation ...

Second order systems with nonlinear nonlocal boundary conditions

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2018
This paper is concerned with the second order differential equation with not necessarily linear nonlocal boundary condition. The existence of solutions is obtained using the properties of the Leray–Schauder degree. The results generalize and improve some

Existence result for a nonlocal viscous Cahn-Hillard equation with a degenerate mobility

open access: yes, 2011
We study a diffusion model of phase field type, consisting of a system of two partial differential equations of second order for the particle densities and the viscosity variable, coupled by a nonlocal drift term.

Spike solutions to a nonlocal differential equation

open access: yesCommunications on Pure and Applied Analysis, 2006
In this paper we consider a nonlocal differential equation, which is a limiting equation of one dimensional Gierer-Meinhardt model. We study the existence of spike steady states and their stability. We also construct a single-spike quasi-equilibrium solution and investigate the dynamics of spike-like solutions.

Finite to infinite steady state solutions, bifurcations of an integro-differential equation

open access: yes, 2011
We consider a bistable integral equation which governs the stationary solutions of a convolution model of solid–solid phase transitions on a circle. We study the bifurcations of the set of the stationary solutions as the diffusion coefficient is varied to ...

On stochastic solutions of nonlocal random functional integral equations

open access: yesArab Journal of Mathematical Sciences, 2019
In this paper, we use Schauder’s fixed point to establish the existence of at least one solution for a functional nonlocal stochastic differential equation under sufficient conditions in the space of all square integrable stochastic processes with a ...

Hyperbolic differential-difference equations with nonlocal potentials [PDF]

open access: yesUfa Mathematical Journal, 2021
Summary: We consider a three-parametric set of solutions for a two-dimensional hyperbolic differential-difference equation in a half-plane containing the sum of a differential operator and shift operators with respect to a spatial variable ranging on the entire real axis (or a differential-difference equation with nonlocal potentials).

Steady-state solutions of a mass-conserving bistable equation with a saturating flux

open access: yes, 2012
We consider a mass-conserving bistable equation with a saturating flux on an interval. This is the quasilinear analogue of the Rubinstein–Steinberg equation, suitable for description of order parameter conserving solid–solid phase transitions in the case
