Gauge Invariance for Nonlinear Master Schrödinger

T. B. Prayitno

We have considered the formulation of gauge invariance for nonlinear master Schrödinger equation. Thisformalism itself is based on the local gauge transformation in which the structure of the theory should be invariant. We alsoredefine the Hamilton-Jacobi and continuity equations constructing the nonlinear master Schrödinger. In the other hand, it isshown that the formulation for including spin concept will not be accepted.
