Splitting and loop theorems in logarithmic Gromov--Witten theory
Leo Herr, David Holmes, Pim Spelier
We define a new theory of logarithmic Gromov--Witten invariants allowing negative contact orders using pierced logarithmic curves. We prove that these classes satisfy logarithmic b…

Functoriality of logarithmic Hochschild homology of log smooth pairs
Ádám Gyenge, Márton Hablicsek, Leo Herr
The construction of a satisfactory dg category of logarithmic coherent sheaves remains a central open problem in logarithmic geometry. In this paper, we propose an alternative corr…
