On the injectivity radius and tangent cones at infinity of gradient Ricci solitons
injectivity radius tangent cones infinity of gradient Ricci solitons
2011/1/18
A lower-bound estimate of injectivity radius for complete Riemannian manifolds is discussed in a pure geometric viewpoint and is applied to study tangent cones at in nity of certain gradient Ricci sol...
Noncommutative (generalized) sine-Gordon/massive Thirring correspondence, integrability and solitons
Noncommutative correspondence integrability solitons
2010/11/10
Some properties of the correspondence between the non-commutative versions of the (generalized) sine-Gordon (NCGSG$_{1,2}$) and the massive Thirring (NCGMT$_{1,2}$) models are studied. Our method rel...
Splitting broad beams into arrays of dissipative spatial solitons by material and virtual gratings
Splitting broad beams arrays dissipative spatial solitons material virtual gratings
2010/11/10
We elaborate two generic methods for producing two-dimensional (2D) spatial soliton arrays (SSAs) in the framework of the cubic-quintic (CQ) complex Ginzburg-Landau (CGL) model. The first approach de...
Band-edge solitons, Nonlinear Schrodinger / Gross-Pitaevskii Equations and Effective Media
Band-edge solitons Nonlinear Schrodinger Gross-Pitaevskii Equations
2010/4/2
We consider a class of nonlinear Schrodinger / Gross-Pitaevskii (NLS/GP) equations with periodic potentials, having an even symmetry. We construct "solitons", centered about any point of symmetry of t...
Twin-vortex solitons in nonlocal nonlinear media
Twin-vortex solitons nonlocal nonlinear media
2010/4/1
We consider soliton formation in thermal nonlinear media bounded by rectangular cross-sections and uncover a new class of nonlinear stationary topological state. Specifically, we find that stationary ...
