Construction of some Quantum Stochastic Operator Cocycles by the Semigroup Method
J. Martin Lindsay, Stephen J. Wills
A new method for the construction of Fock-adapted operator Markovian cocycles is outlined, and its use is illustrated by application to a number of examples arising in physics and…

Quantum Stochastic Operator Cocycles via Associated Semigroups
J. Martin Lindsay, Stephen J. Wills
A recent characterisation of Fock-adapted contraction operator stochastic cocycles on a Hilbert space, in terms of their associated semigroups, yields a general principle for the c…

On The Generators Of Quantum Stochastic Operator Cocycles
Stephen Wills
The stochastic generators of Markov-regular operator cocycles on symmetric Fock space are studied in a variety of cases: positive cocycles, projection cocycles, and partially isome…
