Nonlocal Neumann boundary conditions

open access: yesBruno Pini Mathematical Analysis Seminar, 2023
We present some properties of a nonlocal version of the Neumann boundary conditions associated to problems involving the fractional p-Laplacian. For this problems, we show some regularity results for the general case and some existence results for particular types of problems.

Formulation, analysis and computation of an optimization-based local-to-nonlocal coupling method

open access: yesResults in Applied Mathematics, 2021
We present an optimization-based coupling method for local and nonlocal continuum models. Our approach couches the coupling of the models into a control problem where the states are the solutions of the nonlocal and local equations, the objective is to ...

Impulsive Integrodifferential Equations Involving Nonlocal Initial Conditions [PDF]

open access: yesAdvances in Difference Equations, 2011
The authors study the existence and uniqueness of mild solutions for the Cauchy problem for impulsive Riemann-Liouville integro-differential equations involving non-local initial condition: \[ \begin{gathered} u'(t)- \int^t_0 {(t- s)^{\alpha-2}\over \Gamma(\alpha- 1)} Au(s)\,ds= F(t,u(t)),\quad 0\leq t\leq a,\;t\neq t_1,\\ u(0)= H(u),\\ u(t^+_i)= u(t ...

A third‐order nonlocal problem with nonlocal conditions [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2004
We study an equation with dominated lower‐order terms and nonlocal conditions. Using the Riesz representation theorem and the Schauder fixed‐point theorem, we prove the existence and uniqueness of a generalized solution.

Recovering differential operators with nonlocal boundary conditions [PDF]

open access: yesAnalysis and Mathematical Physics, 2015
Inverse spectral problems for Sturm-Liouville operators with nonlocal boundary conditions are studied. As the main spectral characteristics we introduce the so-called Weyl-type function and two spectra, which are generalizations of the well-known Weyl function and Borg's inverse problem for the classical Sturm-Liouville operator.

Characteristics of off-waist incident anomalous vortex beams in highly nonlocal media

open access: yesResults in Physics, 2017
In this paper, we focus on the effect of the off-waist incident condition on the propagation characteristics of anomalous vortex beams (AVBs) in nonlocal media. An expression is derived mathematically in order to describe the propagation dynamics of AVBs

Conditions for logical contextuality and nonlocality [PDF]

open access: yesPhysical Review A, 2021
Contextuality and nonlocality are nonclassical properties exhibited by quantum statistics whose implications profoundly impact both the foundations and applications of quantum theory. In this paper we provide some insights into logical contextuality and inequality-free proofs.

Multiple solutions of a Sturm-Liouville boundary value problem of nonlinear differential inclusion with nonlocal integral conditions

open access: yesAIMS Mathematics, 2022
The existence of solutions for a Sturm-Liouville boundary value problem of a nonlinear differential inclusion with nonlocal integral condition is studied. The maximal and minimal solutions will be studied.

STATIONARY PROBLEMS WITH NONLOCAL BOUNDARY CONDITIONS

open access: yesMathematical Modelling and Analysis, 2001
In this article a stationary problems with general nonlocal boundary conditions is considered. The differential problems and finite difference schemes for solving this problem are investigated. Stability estimates are proved in the maximum norm and the non‐negativity of the solution is investigated.

Investigation of complex eigenvalues for a stationary problem with two-point nonlocal boundary condition

open access: yesLietuvos Matematikos Rinkinys, 2011
The Sturm–Liouville problem with one classical and another two-point nonlocal boundary condition is considered in this paper. These problems with nonlocal boundary condition are not self-adjoint, so the spectrum has complex points. We investigate how the
