Although generators of strongly continuous semigroups of contractions
on Banach spaces are characterised by the Hille-Yosida theorem, in
practice it can be difficult to verify that this theorem's hypotheses
are satisfied. In this talk, it will be shown how to construct certain
quantum Markov semigroups (strongly continuous semigroups of
contractions on C* algebras) by realising them as expectation
semigroups of non-commutative Markov processes; the extra structure
possessed by such processes is sufficient to avoid the need to use
Hille and Yosida's result.
