Existence of the solution to a nonlocal-in-time evolutional problem [PDF]

open access: yesNonlinear Analysis, 2014
This work is devoted to the study of a nonlocal-in-time evolutional problem for the first order differential equation in Banach space. Our primary approach, although stems from the convenient technique based on the reduction of a nonlocal problem to its ...

Relations between spectrum curves of discrete Sturm-Liouville problem with nonlocal boundary conditions and graph theory

open access: diamondLietuvos Matematikos Rinkinys, 2021
Sturm-Liouville problem with nonlocal boundary conditions arises in many scientific fields such as chemistry, physics, or biology. There could be found some references to graph theory in a discrete Sturm-Liouville problem, especially in investigation of ...

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 ...
