Abstract
Let \(\text {pod}_{9}(n)\), \(\text {ped}_{9}(n)\), and \(\overline {A}_{9}(n)\) denote the number of 9-regular partitions of n wherein odd parts are distinct, even parts are distinct, and the number of 9-regular overpartitions of n, respectively. By considering \(\text {pod}_{9}(n)\) from an arithmetic point of view, we establish a number of infinite families of congruences modulo 16 and 32, and some internal congruences modulo small powers of 3. A relation connecting above partition functions in arithmetic progressions is obtained as follows. For any \(n\geq 0\),
