  • Abstract : I will discuss the mixed-spin-p-fields method for Calabi-Yau quintics. The geometric setup of the method consists of p-fields reformulation of Gromov-Witten theory and FJRW theory, and the usage of master space technique connecting two GIT quotients corresponding to GW and FJRW invariants respectively. This method has been successfully applied to solve BCOV Feynman summation rule for mentioned Calabi-Yau threefolds. I will also discuss some generalisation of the methods to hyper-surfaces in toric varieties.
