On 3D Boltzmann linear operator without cutoff. (Sur l’opérateur de Boltzmann linéaire en dimension 3 sans troncature angulaire.) (French) Zbl 0897.76081

Summary: We show that three-dimensional Boltzmann linear operator, without angular cutoff, can be written as the sum of an elliptic negative operator, and a lower order one. This result holds true for \(s>2\), assuming intermolecular law as \(r^{-s}\).
