Abstract:
In this paper we study a generalized Burgers
equation $u_t+(u^2)_x=tu_{xx}$, which is a non-uniformly parabolic
equation for $t>0$. We show the existence and uniqueness of classical
solutions to the initial value problem of the generalized Burgers
equation with rough initial data belonging to $L^\infty(\R )$.
