  Majorization effect on some entropic functionals, such as von-Neumann,
Shannon, atomic Wehrl and R\'enyi entropies are investigated of a V-type
three-level atom, which interacts with a coherent field in a resonant cavity.
Fidelity, purity and linear entropy are investigated for two quantum systems,
which contain photon number distributions and Husimi Q functions. A relation
between majorization and localization properties of continuous density
functionals is established. The results are compared and verified for
continuous and discrete distributions of an atom-field interacting system.
