Аннотация: We propose a random change of time for a class of generalized di?usion processes such that the corresponding stochastic differential equation (with generalized coe?cients) is transformed into an ordinary one (its coe?cients are some non-generalized functions). It turns out that the latter stochastic differential equation has no property of the (weak) uniqueness of a solution.

Ключевые слова: Diffusion process, random change of time, stochastic differential equation, uniqueness of solution.
