-enumeration of self-complementary plane partitions.
Many links exist between ordinary partitions and partitions with parts in the “gaps”. In this paper, we explore combinatorial explanations for some of these links, along with some natural generalizations. In particular, if we let be the number of partitions of n into j parts where each part is ≡ k (mod m), 1 ≤ k ≤ m, and we let be the number of partitions of n into j parts where each part is ≡ k (mod m) with parts of size k in the gaps, then .
Let be the floor function. In this paper, we prove by asymptotic formula that when , then every sufficiently large positive integer can be represented in the form where , , , , are primes such that .
