Limit theorems for the number of crossings of a fixed plane by certain sequences of generalized dbffusion processes
Ukr. Mat. Zh. - 1994. - 46, № 4. - pp. 357–371
We characterize the weak convergence of certain sequences of generalized diffusion processes by using a specific functional of a process, namely, the number of crossings of a fixed plane by this process.
