Abstract
In this talk, I will prove a formula for the MacDonald index of 4d N=2 SCFTs in terms of the Hilbert series of the arc space of the Zhu algebra of the associated chiral algebra. Using the formula, I will derive a closed form expression for the MacDonald index of (A_1,D_{2n+1}) Argyres-Douglas theories and explain various checks of the formula. The Schur limit of the formula results in a novel q-series identity. I will present a proof of the identity if time permits.
