Summary: | Let Bk, i(n) be the number of partitions of n with certain difference condition and let Ak, i(n) be the number of partitions of n with certain congruence condition. The Rogers–Ramanujan–Gordon theorem states that Bk, i(n)=Ak, i(n). Lovejoy obtained an overpartition analogue of the Rogers–Ramanujan–Gordon theorem for the cases i=1 and i=k. We find an overpartition analogue of the Rogers–Ramanujan–Gordon theorem in the general case. Let Dk, i(n) be the number of overpartitions of n satisfying certain difference condition and Ck, i(n) be the number of overpartitions of n whose non‐overlined parts satisfy certain congruence condition. We show that Ck, i(n)=Dk, i(n). By using a function introduced by Andrews, we obtain a recurrence relation that implies that the generating function of Dk, i(n) equals the generating function of Ck, i(n). By introducing the Gordon marking of an overpartition, we find a generating function formula for Dk, i(n) that can be considered an overpartition analogue of an identity of Andrews for ordinary partitions. |
