Combinatorics of symmetric plabic graphs
Rachel Karpman, Yi Su
A plabic graph is a planar bicolored graph embedded in a disk, which satisfies some combinatorial conditions. Postnikov's boundary measurement map takes the space of positive edge…
Electrical Lie Algebra of Classical Types
Yi Su
We investigate the structure of electrical Lie algebras of finite Dynkin type. These Lie algebras were introduced by Lam-Pylyavskyy in the study of \textit{circular planar electric…
Induced subgraphs in sparse random graphs with given degree sequence
Pu Gao, Yi Su, Nicholas Wormald
For any , we compute the probability that the subgraph of induced by is a given graph on the vertex set . The result holds for any $d=o…
The lattice of integer flows of a regular matroid
Yi Su, David G. Wagner
For a finite multigraph G, let Λ(G) denote the lattice of integer flows of G -- this is a finitely generated free abelian group with an integer-valued positive definite bilinear fo…
