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.

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.

QUANTUM STOCHASTIC EVOLUTIONS WITH NONLOCAL CONDITION

open access: yes, 2015
This work is concerned with nonlocal problem of Quantum stochas- tic evolution of Hudson-Parthasarathy quantum stochastic calculus. By em- ploying fixed point theorem we established the existence and uniqueness of mild and strong solutions of the problem.

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

On the spectrum of a stationary problem with nonlocal integral type boundary condition

open access: yesLietuvos Matematikos Rinkinys, 2004
We investigated a eigenvalue problem for simple second order ordinary differential equation with one inte­gral type nonlocal boundary condition. The eigenvalues and eigenfunctions of such problem are depending on few parameters in the nonlocal boundary ...
