Abstract

Frieden and Soffer conjectured some years ago the existence of a ``Fisher temperature" TF that would play, with regards to Fisher's information measure I, the same role that the ordinary temperature T plays vis-a-vis Shannon's logarithmic measure. Here we exhibit the existence of reciprocity relations between TF and T and provide an interpretation with reference to the meaning of TF for the canonical ensemble.
