CENTRAL SEQUENCE SUBFACTORS AND DOUBLE COMMUTANT PROPERTIES
CENTRAL SEQUENCE SUBFACTORS AND DOUBLE COMMUTANT PROPERTIES
First, we construct the Jones tower and tunnel of the central sequence subfactor arising from a hyperfinite type II 1 subfactor with finite index and finite depth, and prove each algebra has the double commutant property in the ultraproduct of the enveloping II 1 factor. Next, we show the equivalence …
