Singular solutions for the Uehling-Uhlenbeck equation

Miguel Escobedo, Stephane Mischler and Juan J.L. Velazquez


In this paper we prove the existence of solutions of the Uehling-Uhlenbeck equation that behave like k^(-7/6) as k tends to zero. From the physical point of view, such solutions can be thought as particle distributions in the space of momentum having a sink (or a source) of particles with zero momentum. Our construction is based on the precise estimates of the semigroup for the linearized equation around the singular function k^(-7/6) that we obtained in [5].
