Non-asphericity of strata of genus-one differentials and stability spaces

Dawei Chen, Jingyin Huang, Yu Qiu +1

We show that when the number of zeros or poles is at least four, every connected component of the strata of differentials in genus one with prescribed zero and pole orders is not a…

Isoresidual curves

Dawei Chen, Quentin Gendron, Miguel Prado +1

Given a partition $I^¼$ of $- 2$ , the stratum $H (I^¼)$ parametrizes meromorphic differential one-forms on the Riemann sphere $CP^{1}$ with~ $n$ zeros and $p$ poles o…

Independence of tautological classes and cohomological stability for strata of differentials

Dawei Chen, Hannah Larson

The tautological rings of strata of differentials are known to be generated by divisor classes. In this paper, we give lower bounds on the degrees of relations among them, dependin…

Finite isoresidual covers in strata of $k$ -differentials

Dawei Chen, Quentin Gendron, Miguel Prado +1

Consider the strata of primitive $k$ -differentials on the Riemann sphere whose singularities, except for two, are poles of order divisible by $k$ . The map that assigns to each $k$ -…
