In the geometric description, surgery circles and matter circles carry length parameters, while the associated physical parameters are the Fayet–Iliopoulos parameter $xi$ and the m…

Consider a matter node coupled to gauge nodes $ullet_{k_i}$, with charge $q_i$ under each gauge group $U(1)_{k_i}$. The charge $q_i$ is interpreted as the winding number between th…

The plumbing description uses three-manifolds with surgery circles and matter nodes; the charge of a chiral multiplet is interpreted as a winding number. Geometric loop conjecture.…
