Introducing certain singularities, we generalize the class of one-dimensional stochastic differential equations with so-called generalized drift. Equations with generalized drift, well-known in the literature, possess a drift that is described by the semimartingale local time of the unknown...

In this paper, we consider a one-dimensional fractional Brownian motion X and the Fourier transform of its associated Dirac measure δ(X). It is a measure, canonically associated with X (in the sense of Schwartz’s theory of generalized functions). As was shown by Kahane, this measure reflects...

In this paper a k-nearest neighbor type estimator of the marginal density function for a random field which evolves with time is considered. Considering dependence, the consistency and asymptotic distribution are studied for the stationary and nonstationary cases. In particular, the parametric...

We consider a Lévy process reflected in barriers at 0 and K  0. The loss rate is the mean of the local time at K at time 1 when the process is started in stationarity, and is a natural continuous-time analogue of the stationary expected loss rate for a reflected random walk. We derive...
