| dc.description | We construct all instantons in the \nlsig\ on a cylindrical space-time, known not to exist on a finite time interval. The scale parameter, $ρ$, is related to the boundary condition in time. This may cure the $ρ\rightarrow0$ divergent instanton gas, through a proper inclusion of in and out states in the path integral. | |
