Bratteli, Ola, Elliott, George A., Evans, David Emrys and Kishimoto, Akitaka 1994. Finite group actions on AF algebras obtained by folding the interval. K-Theory 8 (5) , pp. 443-464. 10.1007/BF00961400

For any finite groupG we construct examples of an AF algebraA and an action byG onA such that the fixed point algebra is not AF. The construction ofA is done by successive foldings and cuttings of the interval in a way originally suggested by Blackadar and, in a different context, by Connes in his talk in Oslo in 1978.
