A simple sufficient condition for triviality of obstruction in the orbifold construction for subfactors

Authors :: Toshihiko Masuda
Publication Year :: 2015
Abstract: We present a simple sufficient condition for triviality of obstruction in the orbifold construction. As an application, we can show the existence of subfactors with principal graph $D_{2n}$ without full use of Ocneanu's paragroup theory.<br />8pages
