Congruences
for Andrews' Smallest Parts Partition Function and
New Congruences for Dyson's Rank,
Int. J. Number Theory,
6 (2010), no. 2, 1--29.
Abstract:
Let spt(n) denote the total number of appearances of smallest parts in the
partitions of n. Recently, Andrews showed how spt(n) is related to the
second rank moment, and proved some surprising Ramanujan-type congruences
mod 5, 7 and 13. We prove a generalization of these congruences
using known relations between rank and crank moments.
We obtain explicit Ramanujan-type congruences for spt(n) mod p fo
p = 11, 17, 19, 29, 31 and 37.
Recently, Bringmann and Ono proved that Dyson's rank function
has infinitely many Ramanujan-type congruences. Their proof is
non-constructive and utilizes the theory of weak Maass forms.
We construct two explicit nontrivial examples mod 11 using elementary
congruences between rank moments and half-integer weight Hecke eigenforms.
