A sharp upper bound for the expected occupation density of Itô processes with bounded irregular drift and diffusion coefficients
Paul Krühner, Shijie Xu
We find explicit and optimal upper bounds for the expected occupation density for an Itô-process when its drift and diffusion coefficients are unknown under boundedness and ellipti…

Nonlinear attitude stability of a spacecraft on a stationary orbit around an asteroid subjected to gravity gradient torque
Yue Wang, Shijie Xu
The classical problem of attitude stability in a central gravity field is generalized to that on a stationary orbit around a uniformly-rotating asteroid. This generalized problem i…
