Jessica Striker (NDSU): Hourglass plabic graphs and symmetrized six-vertex configurations
Abstract: In this talk, we introduce the title objects and explore their intriguing connections to tableaux dynamics, alternating sign matrices, and plane partitions. In a subsequent talk, we will we discuss the reason we defined these objects, namely, that they index a rotation-invariant SL4-web basis, a long-sought structure. This is joint work with Christian Gaetz, Oliver Pechenik, Stephan Pfannerer, and Joshua P. Swanson.
