定义了酉完全正映射的约化自由积。一个C*-代数上的自同构的不变态（基于自由移位）是一个子代数的态与期望的约化自由积的合成。自同构y的约化自由积和张量积的熵与y的熵一致。
The reduced free product of unital completely positive maps is defined. An invariant state on a C*-algebra for an automorphism (based on the free shift) is the composition of a state of a subalgebra with the reduced free product of expectations. Entropies for the reduced free product and the tensor product of an automorphism y with the free shift coincide with the entropy of y.
