Summary: [For the entire collection see Zbl 0672.00013.]
Under a weak differentiability condition, quantum Markov cocycles on a Fock space satisfy quantum stochastic differential equations of the form \(dV=VF_{\alpha \beta}d\Lambda^{\alpha \beta}\) where \(\{F_{\alpha \beta}\}\) is a matrix of operators with common dense domain, \(\Lambda^{\alpha \beta}\) are the basic martingales of the Hudson- Parthasarathy calculus in n-dimensions and \(\Lambda^{\infty}\) is time.
