Abstract: Ginzburg-Landau equation (GLE) is well known for modeling superconductivity. In this talk, I will introduce the dynamical of quantized vortices of GLE based on particle interaction. I just consider the reduced dynamical laws for time evolution of quantized vortex centers in GLE and show some results of the nonlinear ordinary differential equation (ODE). First, two non-autonomous first integrals of ODE will be given.  According to these first integrals, I discuss the collision of the vortices. Second, I show the dynamical of three vortices completely. Finally, I present several conjecture.
