Markovianity and the Thompson Monoid
Claus Köstler, Arundhathi Krishnan, Stephen J. Wills
We introduce a new distributional invariance principle, called `partial spreadability', which emerges from the representation theory of the Thompson monoid in noncommutative…

Quantum stochastic cocycles and completely bounded semigroups on operator spaces
J. Martin Lindsay, Stephen J. Wills
An operator space analysis of quantum stochastic cocycles is undertaken. These are cocycles with respect to an ampliated CCR flow, adapted to the associated filtration of subspaces…

E-semigroups Subordinate to CCR Flows
Stephen J. Wills
The subordinate E-semigroups of a fixed E-semigroup are in one-to-one correspondence with local projection-valued cocycles of that semigroup. For the CCR flow we characterise these…
