Query: Drifted Brownian motions governed by fractional tempered derivatives   Fractional equations governing the distribution of reflecting drifted
Brownian motions are presented. The equations are expressed in terms of
tempered Riemann--Liouville type derivatives. For these operators a
Marchaud-type form is obtained and a Riesz tempered fractional derivative is
examined, together with its Fourier transform.
