Title: Approximation in the sense of Kato for the transport problem Authors: Mohamed Amine Cherif (Univ. de Poitiers, Cedex, France) Hassan Emamirad (Univ. de Poitiers, Cedex, France) Abstract: Using Chernoff's Theorem, we present an approximation of the family $\{S(t): t\ge 0\}$ that converges in the sense of Kato to the transport semigroup.
