Semilinear integrodifferential equations with nonlocal initial conditions

open access: yesComputers & Mathematics with Applications, 2004
The paper is concerned with developing existence and uniqueness theorems for the Cauchy problem for semilinear integro-differential equations of convolution type. The sequence of theorems presented extends the existing results and can be applied, as is shown in the final section of the paper, to problems that arise in heat conduction in materials with ...

Generalized Green’s functions for second-order discrete boundary-value problems with nonlocal boundary conditions

open access: yesLietuvos Matematikos Rinkinys, 2012
In this paper, generalized Green’s functions for second-order discrete boundaryvalue problems with nonlocal boundary conditions are investigated, where the necessary and sufficient existence condition of discrete Green’s function is not satisfied and ...

Blow-up for a parabolic system with nonlocal sources and nonlocal boundary conditions [PDF]

open access: yesBoundary Value Problems, 2015
This paper deals with blow-up properties of solutions to a nonlocal parabolic system with nonlocal boundary conditions. The global existence and finite time blow-up criteria are obtained. Moreover, for some special cases, we establish the precise blow-up rate estimates.

Nonlinear hyperbolic systems with nonlocal boundary conditions

open access: yesJournal of Mathematical Analysis and Applications, 1987
A nonlinear first-order hyperbolic partial differential equation with nonlocal boundary conditions and subject to an initial condition is studied as a mathematical model for a structured biological population. Its integral form is obtained by integration along the characteristic curves of the differential problem.

Sigma Models and Minimal Surfaces [PDF]

open access: yes, 1997
The correspondance is established between the sigma models, the minimal surfaces and the Monge-Ampere equation. The Lax -Pairs of the minimality condition of the minimal surfaces and the Monge-Ampere equations are given.

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

Boundary Controllability of Differential Equations with Nonlocal Condition

open access: yesJournal of Mathematical Analysis and Applications, 1999
Global exact boundary controllability in a given time-interval of a semilinear abstract dynamical system is considered. It is generally assumed that the dynamical system is defined in an infinite-dimensional Banach space, that it contains both a linear and a nonlinear part, and that, moreover, it satisfies the so-called nonlocal conditions.
