Title:
Fractional quiver gauge theory
Speaker:
Abstract:
We define fractional quiver, and quiver gauge theory associated with it. A key idea is a connection between K-theoretic \Gamma-quiver gauge theory and quiver W-algebra $W_{q_1,q_2}(\Gamma)$. We'd like to show how the non-simply-laced algebra arises from the fractional quiver, and how the fractionalization of quiver variety is discussed. This talk is based on https://arxiv.org/abs/1705.04410 and work in progress with V. Pestun.
