| الوصف: | We show that any two Hadamard subfactors arising from a pair of distinct complex Hadamard matrices of order 3 are either equal or inner conjugate via a unitary in the relative commutant of their intersection. Moreover, when the Hadamard subfactors are not equal, we prove the factoriality of their intersection, and quite interestingly, it turns out to be a vertex model subfactor. We compute the first relative commutant and characterize this subfactor by identifying it with a particular type of Krishnan-Sunder subfactor. A few key invariants, including the Pimsner-Popa probabilistic number, the angle, and the Connes- St{\o}rmer relative entropy for the pair of Hadamard subfactors are computed to understand their relative position. Comment: Minor modification, few typos corrected |
