Mixture estimate arise in the study of well-posedness of solutions to the Boltzmann equations. This property says that some space regularity result will be obtained if one mixes the transport operator and an integral operator with velocity smoothing effect. In this talk we will present this property in fractional sense and apply it to the Boltzmann equation for very soft potentials.
