Preservers for the Tsallis entropy of convex combinations of density operators
Summary: Let \(H\) be a complex separable Hilbert space; we first characterize the unitary equivalence of two density operators by use of Tsallis entropy and then obtain the form of a surjective map on density operators preserving Tsallis entropy of convex combinations.
