, 2003 We review some of our results from the theory of product systems of Hilbert modules. We explain that the product systems obtained from a CP-semigroup in a paper by Bhat and Skeide and in a paper by Muhly and Solel are commutants of each other.

Toward a Classification of Mixed-State Topological Orders in Two Dimensions
PRX QuantumThe classification and characterization of topological phases of matter is well understood for ground states of gapped Hamiltonians that are well isolated from the environment.

Fermionic Magic Resources of Quantum Many-Body Systems
PRX QuantumUnderstanding the computational complexity of quantum states is a central challenge in quantum many-body physics. In qubit systems, fermionic Gaussian states can be efficiently simulated on classical computers and hence can be employed as a natural ...

10-Commutators, 13-commutators and odd derivations
Journal of Nonlinear Mathematical Physics, 2008 Let \(X_1\), \dots, \(X_n\in Vect(n)\) be vector fields on a smooth manifold \(M\) of dimension \(n\) and define the \(N\)-commutator as \(s_N(X_1,\ldots,X_N)=\sum (-1)^\sigma X_{\sigma(1)}\ldots X_{\sigma(N)}\) where the summation runs over the symmetric group \(Sym_N\) and \((-1)^\sigma\) is the sign of the permutation \(\sigma\).

COMMUTANTS AND DOUBLE COMMUTANTS OF REFLEXIVE ALGEBRAS
Kyushu Journal of Mathematics, 1996 The author studies the commutant and the double commutant of the algebra \(\text{alg }{\mathcal L}\) of all bounded operators on a Banach space \(X\) leaving invariant each member of a lattice \({\mathcal L}\) of subspaces of \(X\). For example, he proves that when \({\mathcal L}\) is the pentagon subspace lattice, then the only operators commuting ...
