On the number of simultaneous core partitions with $d$-distinct parts

Abstract

We investigate the number Nd,r(s)N_{d,r}(s) of (s,s+r)(s, s+r)-core integer partitions with dd-distinct parts. Our first main result is a proof of a recurrence relation conjectured by Sahin in 2018. We also derive generating functions, asymptotics, and exact formulas for Nd,r(s)N_{d,r}(s) when rr is within dd of a multiple of ss. Finally, we exhibit a surprising connection to AA-restricted compositions.
