DESCRIPTION:We consider a class of nonlinear Boltzmann equations describin
 g return to thermal equilibrium in a gas of colliding particles suspended 
 in a thermal medium. We study solutions in the space L^1^(*R*^3^x *T*^3^).
  Special solutions of these equations\, called "Maxwellians\," are spatial
 ly homogeneous static Maxwell velocity distributions at the temperature of
  the medium. We prove that\, for dilute gases\, the solutions correspondin
 g to smooth initial conditions in a weighted L^1^-space converge to a Maxw
 ellian in L^1^\, exponentially fast in time. This is a joint work with Jue
 rg Froehlich.\n
