Random Walks on Comb-Type Subsets of Z2

Endre Csáki, Antónia Földes

Research output: Contribution to journalArticle


We study the path behavior of the simple symmetric walk on some comb-type subsets of Z2 which are obtained from Z2 by removing all horizontal edges belonging to certain sets of values on the y-axis. We obtain some strong approximation results and discuss their consequences.
