Let P-3 (n) be the number of overpartition triples of n. By elementary series manipulations, we establish some congruences for P-3(n) modulo small powers of 2, such as P-3(16n+14)≡0 (mod 32), P-3(8n+7)≡0...Let P-3 (n) be the number of overpartition triples of n. By elementary series manipulations, we establish some congruences for P-3(n) modulo small powers of 2, such as P-3(16n+14)≡0 (mod 32), P-3(8n+7)≡0 (mod 64).We also find many arithmetic properties for P-3(n) modulo 7, 9 and 11, involving the following infinite families of Ramanujan-type congruences: for any integers α≥1 and n ≥ 0, we have展开更多
