Intersection Pairings for Higher Laminations
Ian Le
One can realize higher laminations as positive configurations of points in the affine building. The duality pairings of Fock and Goncharov give pairings between higher laminations…

From dimers to webs
Chris Fraser, Thomas Lam, Ian Le
We formulate a higher-rank version of the boundary measurement map for weighted planar bipartite networks in the disk. It sends a network to a linear combination of SL-webs, an…
