Tight Bounds on the Rényi Entropy via Majorization with Applications to Guessing and Compression

This paper provides tight bounds on the Rényi entropy of a function of a discrete random variable with a finite number of possible values, where the considered function is not one to one. To that end, a tight lower bound on the Rényi entropy of a discrete random variable with a finite support is der...
