摘要
Given a pair of inequivalent complex Hadamard matrices of order 4, we construct a potentially new class of infinite depth subfactors. We also examine `two subfactor theory' when the complex Hadamard matrices of order n are equivalent. We apply our results to explicitly construct the value of the corresponding relative entropy and angle operators between the spin model subfactors. Joint work with Satyajit Guin and Guruprasad.
