On spt-crank type functions

Number Theory 2016-10-20 v2

Abstract

In a recent paper, Andrews, Dixit, and Yee introduced a new spt-type function sptω(n)\operatorname{spt}_\omega(n), which is closely related to Ramanujan's third order mock theta function ω(q)\omega(q). Garvan and Jennings-Shaffer introduce a crank function which explains congruences for sptω(n)\operatorname{spt}_\omega(n). In this note, we study asymptotic behavior of this crank function and confirm a positivity conjecture of the crank asymptotically. We also study a sign pattern of the crank and congruences for sptω(n)\operatorname{spt}_\omega(n).
