Abstract
This paper mainly deals with the Cauchy problems for a deformed nonlinear Schrődinger equation, which is a new equation, denoted CH-NLS. Using a Galerkin-type approximation method, it is shown that this equation with is well-posed in Sobolev spaces
on both the line and the circle with continuous dependence on initial data. Moreover, the lower bound of the lifespan and the size of the solution are obtained.
