Semi-Cosimplicial Objects and Spreadability
D. Gwion Evans, Rolf Gohm, Claus Köstler
To a semi-cosimplicial object (SCO) in a category we associate a system of partial shifts on the inductive limit. We show how to produce an SCO from an action of the infinite braid…
A Trotter-Kato Theorem for Quantum Markov Limits
Luc Bouten, Rolf Gohm, John Gough +1
Using the Trotter-Kato theorem we prove the convergence of the unitary dynamics generated by an increasingly singular Hamiltonian in the case of a single field coupling. The limit…
Functional Models and Minimal Contractive Liftings
Santanu Dey, Rolf Gohm, Kalpesh J. Haria
Based on a careful analysis of functional models for contractive multi-analytic operators we establish a one-to-one correspondence between unitary equivalence classes of minimal co…
Weak Markov Processes as Linear Systems
Rolf Gohm
A noncommutative Fornasini-Marchesini system (a multi-variable version of a linear system) can be realized within a weak Markov process (a model for quantum evolution). For a discr…
Noncommutative Independence in the Infinite Braid and Symmetric Group
Rolf Gohm, Claus Köstler
This is an introductory paper about our recent merge of a noncommutative de Finetti type result with representations of the infinite braid and symmetric group which allows to deriv…
Transfer Functions for Pairs of Wandering Subspaces
Rolf Gohm
To a pair of subspaces wandering with respect to a row isometry we associate a transfer function which in general is multi-Toeplitz and in interesting special cases is multi-analyt…
