Abstract
We set up the general relativistic equations of motion of a shell that models the matter ejected in supernova explosions. The non-relativist ic Ostriker-Gunn equation is obtained properly. It is shown that in ge neral the equation of motion admits a first integral and the evolution of the shell is reduced to a dynamical system of four equations.
