#### Abstract

We analyze the nonlinear Schrodinger equation for application to Bose-Einstine condensates. First, we devise a rigorous mathematical model for the underlying physics. We then prove well-posedness and establish sharp bounds for solutions to the equation. Deriving a rigorous model for the dynamics of a general condensate, we then analyse several other physically interesting solutions, particularly radially symmetric and solitary wave solutions. We finally compare these results to experimental Bose-Einstein condensate results, discussing physically interesting details.
