Let po(n) denote the number of overpartitions of n into odd
parts. The partition function po(n) has been the subject of many
recent studies where many explicit Ramanujan-like congruences were discovered.
In this paper, we provide three linear recurrence relation for
po(n). Several connections with partitions into parts not
congruent to 2(mod4), overpartitions and partitions into distinct parts are
presented in this context
