Fence Complexes and Toric Degenerations of Positroid Varieties
Cameron Chang, Pranav Enugandla, Josephine Hlavinka
We associate to each positroid variety in the Grassmannian a polyhedral complex, which we call a fence complex. Fence complexes consist of unions of faces of the…

Clasped web bases from hourglass plabic graphs
Pranav Enugandla, Christian Gaetz
G.-Pechenik-Pfannerer-Striker-Swanson applied hourglass plabic graphs to construct web bases for spaces of tensor invariants of fundamental representations of $U_q(\mathfrak{sl}_4)…
