We propose an explicit formula for the $${{\mathsf {GW}}}/{\mathsf {PT}}$$ GW / PT descendent correspondence in the stationary case for nonsingular connected projective threefolds. The formula, written in terms of vertex operators, is found by studying the 1-leg geometry. We prove the proposal for all nonsingular projective toric threefolds. An application to the Virasoro constraints for the stationary descendent theory of stable pairs will appear in a sequel. 
EGL formula for DT/PT theory of local curves
In this note we prove an integral formula for the bare one-leg PT vertex with descendents. The formula follows from the PT version of Ellingsrud-Gottsche-Lehn formula that is explained here. WeExpand

Virasoro constraints in quantum singularity theories
We introduce Virasoro operators for any Landau-Ginzburg pair (W,G) where W is a non-degenerate quasi-homogeneous polynomial and G is a certain group of diagonal symmetries. We propose a conjectureExpand
