In [Indiana Univ. Math. J. 60 (2011), pp. 847–857] the first author introduced second order necessary conditions for a commuting square to admit sequential deformations in the moduli space of non-isomorphic commuting squares. In this paper we inves

We show that for every prime number p there exist finitely many circulant core complex Hadamard matrices of size p + 1 . The proof uses a ‘derivative at infinity’ argument to reduce the problem to Tao's uncertainty principle for cyclic groups of

Let G be a finite group and denote by CG the commuting square associated to G. The defect of the group G, given by the formula d(G)=∑g∈G|G|order(g), was introduced in [9] as an upper bound for the number of linearly independent directions in whic

We construct new pairs of orthogonal maximal abelian * -subalgebras of M 6 ( C ) , by classifying all self-adjoint complex Hadamard matrices of order 6. In particular, we exhibit a non-affine one-parameter family of non-equivalent Hadamard matrices o

We construct numerous continuous families of irreducible subfactors of the hyperfinite II$_1$ factor, which are non-isomorphic, but have all the same standard invariant. In particular, we obtain 1-parameter families of irreducible, non-isomorphic sub

We consider $\text{\rm II}_1$ factors $L_\mu(G)$ arising from 2-cocyles $\mu \in \text{\rm H}^2(G,\Bbb T)$ on groups $G$ containing infinite normal subgroups $H \subset G$ with the relative property $\text{\rm(T)}$ (i.e. $G$ {\it w-rigid}). We prove
