We prove the following theorem: let A be a UCT Kirchberg algebra, and let a be a prime-order automorphism of K Ã ðAÞ, with að½1 A Þ ¼ ½1 A in case A is unital. Then a is induced from an automorphism of A having the same order as a. This result is extended to certain instances of an equivariant inclu
