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".
