Recurrence and transience of excited random walks on \(\mathbb Z^d\) and strips. (English) Zbl 1112.60086

Summary: We investigate excited random walks on \(\mathbb Z^d\), \(d\geq 1,\) and on planar strips \(\mathbb Z\times\{0,1,\dots,L-1\}\) which have a drift in a given direction. The strength of the drift may depend on a random i.i.d. environment and on the local time of the walk. We give exact criteria for recurrence and transience, thus generalizing results by I. Benjamini and D. B. Wilson [Electron. Commun. Probab. 8, 86–92 (2003; Zbl 1060.60043)] for once-excited random walk on \(\mathbb Z^d\) and by the author [Probab. Theory Relat. Fields 133, No. 1, 98–122 (2005; Zbl 1076.60088)] for multi-excited random walk on \(\mathbb Z\).
