Reaction Diffusion Equations with Nonlocal Boundary and Nonlocal Initial Conditions

open access: yesJournal of Mathematical Analysis and Applications, 1995
The author considers the existence, multiplicity, and asymptotic behavior of solutions for a reaction diffusion equation under nonlocal boundary and nonlocal initial conditions. The main results are the theorems about the existence of multiple solutions for both the time-dependent and the steady-state problems, and that each of the time-dependent ...

On Nonclassical Impulsive Ordinary Differential Equations with Nonlocal Conditions

open access: yesInternational Journal of Analysis and Applications, 2019
Results on mild solutions of nonclassical differential equations with impulsive and nonlocal conditions are extended to a case when the nonlocal conditions are necessarily non Lipschitz and non compact.

A Nonlocal Problem with Integral Conditions for a Hyperbolic Equation

open access: yesDifferential Equations, 2004
One considers a Cauchy problem for the two dimensional hyperbolic equation where the solution has to verify a nonlocal integral condition, too. The stated problem cannot be reduced to a boundary value problem. Under certain conditions one proves a priori estimates and the existence and uniqueness of solutions in a Sobolev space.

Positive solutions of a boundary value problem with integral boundary conditions [PDF]

open access: yesElectronic Journal of Differential Equations, 2011
We consider boundary-value problems studied in a recent paper. We show that some existing theory developed by Webb and Infante applies to this problem and we use the known theory to show how to find improved estimates on parameters $mu^*, lambda ...

Nonlocal Mixed Systems With Neumann Boundary Conditions [PDF]

open access: yesMathematical Methods in the Applied Sciences
ABSTRACTWe prove well posedness and stability in for a class of mixed hyperbolic–parabolic nonlinear and nonlocal equations in a bounded domain with no flow along the boundary. While the treatment of boundary conditions for the hyperbolic equation is standard, the extension to of classical results about parabolic equations with Neumann conditions ...

On the nonlocal Cahn–Hilliard equation with nonlocal dynamic boundary condition and boundary penalization [PDF]

open access: yesJournal of Differential Equations, 2021
The Cahn--Hilliard equation is one of the most common models to describe phase segregation processes in binary mixtures. In recent times, various dynamic boundary conditions have been introduced to model interactions of the materials with the boundary more precisely.
