Two congruences involving 4-cores

open access: yes, 1996
. The goal of this paper is to prove two new congruences involving 4-cores using elementary techniques; namely, if a4(n) denotes the number of 4-cores of n, then a4(9n+2) j 0 (mod 2) and a4(9n + 8) j 0 (mod 4).

open access: yes, 2003
Dyson defined the rank of a partition (as the first part minus the number of parts) whilst investigating certain congruences in the sequence p−1(n). The rank has been widely studied as have been other statistics, such as the crank.

. Let p(n) be the number of partitions of an integer n. Euler proved the following recurrence for p(n): p(n) = (−1) k+1 p n−ω(k) +p n−ω(−k) k=1 where ω(k) = 3k2 +k /2.
