Authors consider in the space the transport operator. To obtain the representation of the solution of the equation authors introduce some integral (like known expression the semigroup by the resolvent) and prove directly that this integral is corresponding semigroup. To simplify the calculus the authors reduce the operator L to some Friedrichs' model using Fourier transformation.
