BCOV's Feynman rule of quintic -folds
Huai-Liang Chang, Shuai Guo, Jun Li
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 the…
Polynomial structure of Gromov-Witten potential of quintic -folds via NMSP
Huai-Liang Chang, Shuai Guo, Jun Li
We use stable graphs to package the relations. Our tools are the matrix of the -twisted equivariant GW theory, and th…
The theory of N-Mixed-Spin-P fields
Huai-Liang Chang, Shuai Guo, Jun Li +1
This is the first part of the project toward proving the BCOV's Feymann graph sum formula of all genera Gromov-Witten invariants of quintic Calabi-Yau threefolds. In this paper, we…
Algebraic virtual cycles for quantum singularity theories
Huai-Liang Chang, Young-Hoon Kiem, Jun Li
We construct algebraic virtual cycles that give us the cohomological field theories of Fan-Jarvis-Ruan invariants by integral transformations.
Invariants of stable quasimaps with fields
Huai-Liang Chang, Mu-lin Li
For an arbitrary smooth hypersurface X in a projective space, we construct its LG moduli of quasimaps with P fields. Apply Kiem-Li's cosection localization we obtain a virtual fund…
