Splitting formulas for the logarithmic double ramification cycle
Pim Spelier
The logarithmic double ramification cycle is roughly a logarithmic Gromov--Witten invariant of . For classical Gromov--Witten invariants, formulas for the pullback al…

The log Grothendieck ring of varieties
Andreas Gross, Leo Herr, David Holmes +2
We define a Grothendieck ring of varieties for log schemes. It is generated by one additional class ``'' over the usual Grothendieck ring. We show the naïve definition of log Ho…

Logarithmic tautological rings of the moduli spaces of curves
Rahul Pandharipande, Dhruv Ranganathan, Johannes Schmitt +1
We define the logarithmic tautological rings of the moduli spaces of Deligne-Mumford stable curves (together with a set of additive generators lifting the decorated strata classes…
