我们介绍了修改Voiculescu的自由熵,这符合的极限inf变量Voiculescu的自由熵的极端状态,但凹上半连续函数的轨迹状态空间。我们还扩展了Hiai等人的轨道自由熵。(2009)[8]到非超有限多变量,并证明在Voiculescu熵的可加性(或我们的扩展轨道熵的消失)的情况下的自由度。
We introduce a modification of Voiculescu’s free entropy which coincides with the lim inf variant of Voiculescu’s free entropy on extremal states, but is a concave upper semi-continuous function on the trace state space. We also extend the orbital free entropy of Hiai et al. (2009) [8] to non-hyperfinite multivariables and prove freeness in the case of additivity of Voiculescu’s entropy (or vanishing of our extended orbital entropy).
