DESCRIPTION:Yalong Cao (Riken)\nI will start by reviewing an old joint wor
 k with Davesh Maulik and Yukinobu Toda on relating Gromov-Witten\, Gopakum
 ar-Vafa (in the sense of Klemm-Pandharipande) and stable pair invariants o
 n compact Calabi-Yau 4-folds. For non-compact CY4 like local curves\, simi
 lar invariants can be studied via the perspective of quasimaps to quivers 
 with potentials. In a recent joint work with Gufang Zhao\, we define a vir
 tual count for such quasimaps and prove a gluing formula. Computations of 
 examples will also be discussed.\n
