Query: diffstrata -- a Sage package for calculations in the tautological ring
  of the moduli space of Abelian differentials   The boundary of the multi-scale differential compactification of strata of
abelian differentials admits an explicit combinatorial description. However,
even for low-dimensional strata, the complexity of the boundary requires use of
a computer. We give a description of the algorithms implemented in the SageMath
package diffstrata to enumerate the boundary components and perform
intersection theory on this space. In particular, the package can compute the
Euler characteristic of strata using the methods developed by the same authors
in [CMZ20].
