This is the second part of the project toward an effective algorithm to evaluate all genus
Gromov-Witten invariants of quintic Calabi-Yau threefolds. In this paper, the localization …

We prove the BCOV Feynman rule by identifying the Feynman graph sum to the graph sum
of an R-matrix action extracted from the NMSP theory. As direct consequences,(i) we obtain …

We study genus 1 Gromov-Witten invariants of Fano complete intersections in the projective
spaces. Among other things, we show a reconstruction theorem for genus 1 invariants with …

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 …

We study one-parameter deformations of Calabi-Yau type Fermat polynomial singularities
along degree-one directions. We show that twisted sectors in the vanishing cohomology are …

This is a survey of using NMSP method to study higher genus Gromov-Witten invariants of
Calabi-Yau quintics. It emphasizes on how and why the various methods are introduced to …
