Fisher information in a Tsallis non-extensive environment

The past decade has witnessed an impressive growth in the scope and variety of physical applications of Fisherʹs information measure (FIM). In the present effort we study a similar measure, but defined within the strictures of Tsallisʹ non-extensive scenarios. It is seen that this new measure exhibits interesting relations linking it to both Tsallisʹ and Renyiʹs ones.
