Statistically characterized subgroups related to arithmetic-type sequence of integers
Pratulananda Das, Ayan Ghosh, Tamim Aziz
Very recently, in [Das et al., J. Lond. Math. Soc., 2025], statistically characterized subgroups were studied for certain classes of non-arithmetic sequences. Subsequently, in [Das…
