Ergodic Theorems for Random Walks in Random Environments
Ayan Ghosh
We study the Ergodic Properties of Random Walks in stationary ergodic environments without uniform ellipticity under a minimal assumption. There are two main components in our work…

Characterizing infinite torsion subgroups of the circle through arithmetic-type sequences
Ayan Ghosh, Pratulananda Das
In a recent work [Das et al., Bull. Sci. Math. 199 (2025), 103580], the structure of characterized subgroups corresponding to arithmetic-type sequences was investigated. Building u…

Statistically characterized subgroups related to some non-arithmetic sequence of integers II (a quest for countable subgroups)
Pratulananda Das, Ayan Ghosh, Tamim Aziz
Following the work of [Dikranjan et al., Fund. Math. 249:185-209, 2020] for arithmetic sequences, very recently in [Das et al., Expo. Math. 43(3):125653, 2025], statistically chara…
