导出了Tsallis相对熵的Pinsker和Fannes型界.量子$f$ -发散的单调性性质用于从下面估计它。对于$α\in(0,1)$阶，得到了一族Pinsker型下界.对于$α>1$和交换的情况下，相对熵的最小概率在其第二个参数的上连续性界的推导。的下限和上限提出的情况下，雷尼熵重新制定。将Fano不等式推广到所有$α>0$的Tsallis熵.推导出的Tsallis条件熵的界用于获得Fannes型不等式。
英文摘要：
Pinsker's and Fannes' type bounds on the Tsallis relative entropy are derived. The monotonicity property of the quantum $f$-divergence is used for its estimating from below. For order $α\in(0,1)$, a family of lower bounds of Pinsker type is obtained. For $α>1$ and the commutative case, upper continuity bounds on the relative entropy in terms of the minimal probability in its second argument are derived. Both the lower and upper bounds presented are reformulated for the case of Rényi's entropies. The Fano inequality is extended to Tsallis' entropies for all $α>0$. The deduced bounds on the Tsallis conditional entropy are used for obtaining inequalities of Fannes' type.
