Resumen:
We show that typical Renyi´s statistical mechanics´ quantifiers exhibitpoles. We are referring to the partition function ${cal Z}$ and the meanenergy $$. Renyi´s entropy is characterized by a realparameter $alpha$. The poles emerge in a numerable set ofrational numbers belonging to the $alpha-$line. Physical effectsof these poles are studied by appeal to dimensionalregularization, as usual.Interesting effects are found, as for instance, gravitationalones. In particular, negative specific heats.
