The tautologicality conjecture for effective classes of a logarithmic target

At least 3 years old · documented by

Let ∞X\infty_\mathcal{X} be a logarithmic target with Gromov--Witten classes, and let ∞\infty be the associated target whose effective classes are under consideration. A class is tautological in cohomology (resp. Chow) when it lies in the corresponding tautological ring. Tautologicality conjecture. If ∞X\infty_\mathcal{X} has tautological Gromov--Witten classes in cohomology (resp. Chow), then effective classes of ∞\infty are tautological in cohomology (resp. Chow). This would give a strong connection between tautological Gromov--Witten classes and effective classes; the supplied text does not indicate whether the assertion has been proved or disproved.
