Abstract
Position–momentum uncertainty in Nelson’s stochastic mechanics [Phys. Rev. 1 5 0, 1079 (1966)] has previously been investigated by de la Peña‐Auerbach and Cetto [Phys. Lett. A 3 9, 65 (1972)]. In this paper their result is generalized, and full equivalence between the uncertainty relations in stochastic mechanics and conventional quantum mechanics is established. Force–momentum uncertainty is also considered.
