Eskin–Zorich large-genus volume conjecture for strata of differentials

Let gg tend to infinity, let k=(k1,,kn)\boldsymbol{\boldsymbol{k}}=(k_1,\ldots,k_n) be a partition of 2g22g-2, and write Vol(k1,,kn){\rm Vol}(k_1,\ldots,k_n) for the volume of the corresponding stratum. Define the error term ϵ1(μ)\epsilon_1(\mu) by the asserted asymptotic formula. Eskin–Zorich's volume conjecture. The volumes of strata satisfy

Vol(k1,,kn)=4(k1+1)(k2+1)(kn+1)(1+ϵ1(μ)),{\rm Vol}(k_1,\ldots,k_n)=\frac{4}{(k_1+1)(k_2+1)\cdots(k_n+1)}(1+\epsilon_1(\mu)),

where

limg(maxμ2g2ϵ1(μ))=0.\lim_{g\to\infty}\left(\max_{\mu\vdash 2g-2}|\epsilon_1(\mu)|\right)=0.

This predicts a uniform large-genus asymptotic across all strata of Abelian differentials. The paper proves the corresponding asymptotic for the principal stratum and for the stratum with one zero, but the uniform statement for all strata remains open in the source.
