P. Feinsilver et al., FEYNMAN-KAC FORMULA AND APPELL SYSTEMS ON QUANTUM GROUPS, Comptes rendus de l'Academie des sciences. Serie 1, Mathematique, 321(12), 1995, pp. 1615-1619
We construct analogues of certain stochastic processes on R(tau), e.g.
, Brownian motion, on quantum groups. For the analogue of Brownian mot
ion, we present a Feynman-Kac type formula. Appell systems are defined
and shown to be solutions of differential-difference equations.
