Nonlocal incoherent solitons [PDF]
We investigate the propagation of partially coherent beams in spatially nonlocal nonlinear media with a logarithmic type of nonlinearity. We derive analytical formulas for the evolution of the beam parameters and conditions for the formation of nonlocal ...

Solitons in Nonlinear Media with an Infinite Range of Nonlocality: First Observation of Coherent Elliptic Solitons and of Vortex-Ring Solitons [PDF]
We present an experimental study on wave propagation in highly nonlocal optically nonlinear media, for which far-away boundary conditions significantly affect the evolution of localized beams.

Difference Schemes with Nonlocal Boundary Conditions
AbstractThe paper deals with the stability, with respect to initial data, of difference schemes that approximate the heat-conduction equation with constant coefficients and nonlocal boundary conditions. Some difference schemes are considered for the one-dimensional heat-conduction equation, the energy norm is constructed, and the necessary and ...

NONLINEAR VARIATIONAL EVOLUTION INEQUALITIES WITH NONLOCAL CONDITIONS [PDF]
The authors prove existence, uniqueness and regularity results for the following nonlinear functional differential problem with nonlocal initial condition: \[ \frac{d}{dt} x(t)+Ax(t)+ \partial\Phi\bigl(x(t)\bigr)\ni f \bigl(t,x(t)+k(t),\bigr),\quad 00\), \(k\in L^2(0,T:H)\) and \(x_0\in\overline{D(\Phi)}\).

Hypothesis on the Solvability of Parabolic Equations with nonlocal Condition
Numerous and different nonlocal conditions for the solvability of parabolic equations were researched in many articles and reports. The article presented analyzes such conditions imposed, and observes that the existence and uniqueness of the solution of ...
