dc.descriptionWe construct all instantons for the \nlsig\ on a cylinder, known not to exist on a finite time interval. We show that the widest instantons go through sphalerons. A re-interpretation of moduli-space transforms the scale parameter $ρ$ to a boundary condition in time. This may give a handle on the $ρ\rightarrow0$ divergent instanton gas.
