Abstract
We study the one dimensional nonlinear Schrödinger equation with power nonlinearity | u| α-1u for α∈ [1 , 5] and initial data u∈ H1(T) + L2(R). We show via Strichartz estimates that the Cauchy problem is locally well-posed. In the case of the quadratic nonlinearity (α= 2) we obtain global well-posedness in the space C(R, H1(T) + L2(R)) via Gronwall’s inequality.
