Title: Shrubby quivers on the torus and quantum loop groups


Abstract: Algebraic structures behind BPS counting on toric Calabi-Yau 
threefolds have recently been realized mathematically in terms of the 
quantum loop group associated to a certain quiver drawn on a torus. In 
this talk, we give a generators-and-relations presentation of the 
reduced version of this quantum loop group, assuming the quiver 
satisfies a technical condition we call "shrubbiness".
