Blowing up time-dependent solutions of the planar, Chern-Simons gauged nonlinear Schrödinger equation. (English) Zbl 0822.35125
Summary: Time-dependent solutions of the two-dimensional Chern-Simons gauged nonlinear Schrödinger equation are investigated in terms of an initial- value problem. We prove that this Cauchy problem is locally well posed in $H\sp 2 (\bbfR\sp 2)$, and that global solutions exist in $H\sp 1 (\bbfR\sp 2)$ provided that the initial data are small enough in $L\sp 2 (\bbfR\sp 2)$. On the other hand, under certain conditions ensuring, for example a negative Hamiltonian, solutions blow up in a finite time which only depends on the initial data. The diverging shape of collapsing structure is finally discussed throughout a self-similar analysis.
