Abstract

Motivated by the article [M. Takei, Electron. J. Probab. 26 (2021), article no. 104], we study the limit behavior of linearly edge-reinforced random walks on the half-line Z+\mathbb{Z}_+ with reinforcement parameter δ>0\delta>0, and each edge {x,x+1}\{x,x+1\} has the initial weight xαlnβxx^{\alpha}\ln^{\beta}x for x>1x > 1 and 11 for x=0,1x = 0, 1. The aim of this paper is to study the almost sure limit behavior of the walk in the recurrent regime, and extend the results of Takei mentioned above.
