摘要：
Motivated by Voiculescu's liberation theory, we introduce the orbital free entropy chi(orb) for non-commutative self-adjoint random variables (also for "hyperfinite random multivariables"). Besides its basic properties, the relation of chi(orb) with the usual free entropy. is shown. Moreover, the dimension counterpart delta(0,orb) of chi(orb) is discussed, and we obtain the relation between delta(0,orb) and the original free entropy dimension delta(0) together with applications to delta(0) itself.
