The dynamical properties of radial-variant vector beams in strongly nonlocal nonlinear (SNN) media are theoretically demonstrated. The analytical expressions for the variation of root-mean-square (RMS) beam width and the critical powers Pcr that keep the RMS beam widths invariant during propagation...
