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…

On the -theoretic logarithmic double ramification class
Kamyar Amini, You-Cheng Chou, Leo Herr +3
The paper defines a K‑theoretic version of the logarithmic double ramification class, proves a product formula and GLₙ(ℤ)‑invariance, and provides an explicit expression using Grot…
