论文摘要
我们证明了佩德森（Pedersen）的外部共轭定理的一种版本，用于紧凑型组的共同体，该版本以双重动作的性质来表征紧凑型组的外部共轭共同体。实际上，我们表明，双重动作的每一个同构都均来自共同的独特的外部结合，在这种情况下，该偶像性应称为强大的PEDERSEN刚性。我们将其提升为类别的等效性。
We prove a version of Pedersen's outer conjugacy theorem for coactions of compact groups, which characterizes outer conjugate coactions of a compact group in terms of properties of the dual actions. In fact, we show that every isomorphism of a dual action comes from a unique outer conjugacy of a coaction, which in this context should be called strong Pedersen rigidity. We promote this to a category equivalence.
