Abstract
In an attempt to find a connection between the statistical entropy and the spectral entropy proposed by Powell and Percival, these propertie s are explicitly computed and compared for three different systems: Br ownian motion of a particle in a fluid, Brownian motion in a harmonic potential, and the photon gas. It is shown that in these systems the s tatistical and the spectral entropy compare weakly since they quantify different statistical aspects.
