The many faces of a logarithmic scheme
Thibault Poiret, Dhruv Ranganathan
A standard assumption in the study of logarithmic structures is "fineness", but this assumption is not preserved by intersections, fiber products, and more general limits. We expla…
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…
Combinatorics of Hurwitz degenerations and tropical realizability
Mia Lam, Chi Kin Ng, Dhruv Ranganathan
We investigate the realizability of balanced functions on tropical curves, establishing new sufficient criteria for superabundant functions on genus two curves, analogous to the we…
Logarithmic negative tangency and root stacks
Luca Battistella, Navid Nabijou, Dhruv Ranganathan
We study stable maps to normal crossings pairs with possibly negative tangency orders. There are two independent models: punctured Gromov-Witten theory of pairs and orbifold Gromov…
