Hypersimplex harmonics — interactive demos
Companion to Graded Ehrhart Theory for Hypersimplices. Draw a loopless multigraph G below. Each tab runs a different construction from the paper on it. Click empty space to add a vertex, click two vertices to connect (click a pair again for a parallel edge); switch the mode button to delete. You can also type the edge list directly. Email me if you find any errors or want some specific function added.
blocks, cut-edges and deficits
edges — editable; e.g.
(1,3),(2,4),(3,4)x2 or 1-3 2-4 3-4 3-4 Express δG as an exact integer combination of products of m degree-1 (matching) tableaux, verify the identity, and report the structures that obstruct writing δG as a single such product.
