On Measure Solutions of the Boltzmann Equation part I: Moment Production and Stability Estimates
Résumé
The spatially homogeneous Boltzmann equation with hard potentials is considered for measure valued initial data having finite mass and energy. Moment production estimates in the usual form and in the exponential form are obtained for measure solutions with and without angular cutoff on the collision kernel. For the Grad angular cutoff, it is also established the strong stability estimate for measure solutions.
