  We study in great detail the possible existence of a Renyi-associated
thermodynamics, with negative results. In particular, we uncover a hidden
relation in the Renyi's variational problem (MaxEnt). This relation connects
the two associated Lagrange multipliers (Canonical Ensemble) with the mean
energy $<U>$ and the Renyi parameter $\alpha$. As a consequence of such
relation, we obtain anomalous Renyi-MaxEnt thermodynamic results.
