Phys. Lett., A 372, No. 46, 6823-6825 (2008).

Summary: Connection between Fisher information and Rényi entropy has been established. This link allows us to define the Fisher-Rényi information plane and an entropic product in terms of these quantities. New Rényi uncertainty relations are obtained for single particle densities of many particle systems in position-momentum conjugate spaces.
