摘要：
In 2012, Lin (Electron. J. Combin. 19(2) (2012) #P17) investigated the 2 and 3-divisibility properties for (pp) over bar (o)(n), the number of overpartition pairs into odd parts. Using modular forms, he proved that for a fixed positive integer k, (pp) over bar (o)(n) is almost always divisible by 2(k). In this paper, we prove several congruences for (pp) over bar (o)(n) modulo higher powers of 2 in an elementary way. (C) 2018 Elsevier B.V. All rights reserved.
