From -spin to Negative -spin: Limits of Cohomological Field Theories and Tautological Relations

Deniz Genlik, Felix Janda

We prove that the negative -spin tautological relations of Chidambaram--Garcia-Failde--Giacchetto are a consequence of Pixton's -spin relations, for every , and deduce…

Punctured logarithmic R-maps

Qile Chen, Felix Janda, Yongbin Ruan

In this paper, we develop the theory of punctured R-maps as a crucial component of logarithmic gauged linear sigma models (log GLSM). A punctured R-map is a punctured map in the se…

Virtual cycles of stable (quasi)-maps with fields

Qile Chen, Felix Janda, Rachel Webb

We generalize the results of Chang-Li, Kim-Oh and Chang-Li on the moduli of -fields to the setting of (quasi-)maps to complete intersections in arbitrary smooth Deligne-Mumford…

The logarithmic gauged linear sigma model

Qile Chen, Felix Janda, Yongbin Ruan

We introduce the notion of log R-maps, and develop a proper moduli stack of stable log R-maps in the case of a hybrid gauged linear sigma model. Two virtual cycles (canonical and r…

Structure of Higher Genus Gromov-Witten Invariants of Quintic 3-folds

Shuai Guo, Felix Janda, Yongbin Ruan

There is a set of remarkable physical predictions for the structure of BCOV's higher genus B-model of mirror quintic 3-folds which can be viewed as conjectures for the Gromov-Witte…

Pixton's double ramification cycle relations

Emily Clader, Felix Janda

We prove a conjecture of Pixton, namely that his proposed formula for the double ramification cycle on Mbar_{g,n} vanishes in codimension beyond g. This yields a collection of taut…
