We use a local discontinuous Galerkin method to solve the nonlinear Schr odinger equation.Numerical investigations for bright soliton, dark soliton and rogu
In this talk, we consider a model for the interaction of a gas with photons.In the early work, smooth traveling wave solutions called shock profiles have be
The global existence and structures of solutions to multi-dimensional pressure gradient system has some open problems.In this paper, we construct global cla
We show that massless Dirac waves in the Schwarzschild geometry decay at a rate t(-21), where t is the angular momentum.Our technique is to use Chandrasekha
