TOI-1842b: A Transiting Warm Saturn Undergoing Re-Inflation around an Evolving Subgiant
Robert A. Wittenmyer, Jake T. Clark, Trifon Trifonov +41
The imminent launch of space telescopes designed to probe the atmospheres of exoplanets has prompted new efforts to prioritise the thousands of transiting planet candidates for fol…
On weak solution of SDE driven by inhomogeneous singular Lévy noise
Tadeusz Kulczycki, Alexei Kulik, Michał Ryznar
We study a time-inhomogeneous SDE in driven by a cylindrical Lévy process with independent coordinates which may have different scaling properties. Such a structure of the d…
On regularization by a small noise of multidimensional ODEs with non-Lipschitz coefficients
Alexei Kulik, Andrey Pilipenko
In this paper we solve a selection problem for multidimensional SDE , where the drift and diffu…
Gradient formula for transition semigroup corresponding to stochastic equation driven by a system of independent Lévy processes
Alexei Kulik, Szymon Peszat, Enrico Priola
Let be the transition semigroup of the Markov family defined by SDE where is a syste…
Construction and heat kernel estimates of general stable-like Markov processes
V. Knopova, A. Kulik, R. Schilling
A stable-like process is a Feller process taking values in and whose generator behaves, locally, like an -stable Lévy process, but the index …
Moment bounds for dissipative semimartingales with heavy jumps
Alexei Kulik, Ilya Pavlyukevich
In this paper we show that if large jumps of an Itô-semimartingale have a finite -moment, , the radial part of its drift is dominated by for some , a…
