Resumen:

The completed volumes were introduced by Duriev-Goujard-Yakovlev as an approximation to compute Masur-Veech volumes via Witten-Kontsevich's combinatorial classes. We show that these volumes agree with the top intersection of the tautological class on the double ramification cycle, which is computable as a coefficient of a Chiodo class.

This is joint work with Martin Moeller.
