Conti, Roberto; D’Antoni, Claudio Extension techniques in \(C^*\)-cross products by compact group duals and in quantum field theory. (English) Zbl 1035.81032 Electron. J. Differ. Equ. 2000, Conf. 04, 23-35 (2000). Summary: Using the methods developed in a previous paper [Rev. Math. Phys. 12, 725–738 (2000; Zbl 1044.81083)], we consider the problem of extending endomorphisms to cross-product by compact group duals getting a result of M. Müger [Ann. Inst. Henri Poincaré Phys. Théor. 71, 359–394 (1999; Zbl 0938.81018)]. Then we discuss some other applications to quantum field theory, mainly in connection with PCT symmetries.
