Recurrence and transience of random walks with drift $ρ x^{α} / t^{β}$

Ngo P. N. Ngoc, Tuan-Minh Nguyen

Menshikov and Volkov [Electron. J. Probab. 13 (2008)] studied recurrence and transience of a class of Markovian random walks on $R_{+}$ whose conditional drift depends on bot…

Limit theorems for random walks with spatio-temporal drift

Ngo P. N. Ngoc, Tuan-Minh Nguyen

We study a class of discrete-time random walks in $R^{d}$ whose conditional drift decays polynomially in time and grows polynomially with the distance from the origin to the…

Open interacting particle systems and Ising measures

Ngo P. N. Ngoc, Gunter M. Schütz

We first survey some open questions concerning stochastic interacting particle systems with open boundaries. Then an asymmetric exclusion process with open boundaries that generali…
