DESCRIPTION:We consider a class of nonlinear Boltzmann equatio
 ns describing return to thermal equilibrium in a g
 as of colliding particles suspended in a thermal m
 edium. We study solutions in the space L^1^(*R*^3^
 x *T*^3^). Special solutions of these equations\, 
 called "Maxwellians\," are spatially homogeneous s
 tatic Maxwell velocity distributions at the temper
 ature of the medium. We prove that\, for dilute ga
 ses\, the solutions corresponding to smooth initia
 l conditions in a weighted L^1^-space converge to 
 a Maxwellian in L^1^\, exponentially fast in time.
  This is a joint work with Juerg Froehlich.\n
