The stochastic Weiss conjecture is the statement that for linear stochastic evolution equations governed by a linear operator $ A $ and driven by a Brownian motion, a necessary and sufficient condition for the existence of an invariant measure can be given in terms of the operators $ \sqrt{\lambda}(\lambda-A)^{-1} $. Such a condition is presented in the special case where $ -A $ admits a bounded $ H^\infty $-calculus of angle less than $ \pi/2 $. This is joint work with Jamil Abreu and Bernhard Haak.
