Automorphisms of the bipartite graph planar algebra

R. D. Burstein

For any abstract subfactor planar algebra $P$ , there exists a finite index extremal subfactor $M_{0} \subset M_{1}$ with $P$ as its standard invariant. In this paper, we classify the a…

Group-type subfactors and Hadamard matrices

Richard D. Burstein

A hyperfinite $I I_{1}$ subfactor may be obtained from a symmetric commuting square via iteration of the basic construction. For certain commuting squares constructed from Hadamard ma…

Commuting-Square Subfactors and Central Sequences

Richard Burstein

Let $M_{0} \subset M_{1}$ be a finite-index infinite-depth hyperfinite $I I_{1}$ subfactor and $ω$ a free ultrafilter of the natural numbers. We show that if this subfactor is constructed…
