Solitons in combined linear and nonlinear lattice potentials
Solitons nonlinear lattice potentials combined linear
2010/4/1
We study ordinary solitons and gap solitons (GSs) in the effectively one-dimensional Gross-Pitaevskii equation, with a combination of linear and nonlinear lattice potentials. The main points of the an...
Dykstra’s Algorithm as the Nonlinear Extension of Bregman's Optimization Method
Bregman projection convex programming Dykstra's algorithm
2009/1/22
We show that Dykstra's algorithm with Bregman projections, which finds the Bregman projection of a point onto the nonempty intersection of finitely many closed convex sets, is actually the nonlinear e...
Existence of a Continuous Solution of Parametric Nonlinear Equation with Constraints
Continuous Solution Parametric Nonlinear Equation Constraints
2009/1/16
Combining a consequence of the Michael continuous selection theorem and an iterative scheme we prove the existence of a continuous solution of a parametric equation with constraints. An inverse functi...
Homographic Approximation for Some Nonlinear Parabolic Unilateral Problems
Homographic Nonlinear Parabolic Unilateral Problems
2009/1/15
We deal with nonlinear parabolic unilateral problems by means of the homographic approximation, introduced by C. M. Brauner and B. Nicolaenko [in: "Nonlinear Partial Diff. Equations and Their Applicat...
