Homomesy of Tropical -systems: Finite Type
Ariana Chin, Pavlo Pylyavskyy
In 2007, Fomin and Zelevinsky introduced the bipartite belt, a sequence of bipartite cluster mutations whose exchange relations form a discrete dynamical system. For each Dynkin di…
Matrix-tree theorem for cohomological electrical networks
Pavlo Pylyavskyy, Svetlana Shirokovskikh, Mikhail Skopenkov
We introduce a new type of boundary condition for electrical networks by specifying a cohomology class on the underlying cell complex. As special and limiting cases, we recover the…
Paths and Intersections: Repelling Pairs
Yu Chen, Pavlo Pylyavskyy, Zihan Tan
We study two inverse problems for shortest-path metrics of Okamura-Seymour instances: recognizing metrics realizable by outerplanar graphs, and computing minimum-edge Okamura-Seymo…
Temperley-Lieb Immanants of Ribbon Decomposition Matrices
Son Nguyen, Pavlo Pylyavskyy
Ribbon decomposition matrices give determinantal formulas for skew Schur functions that include as special cases the classical Jacobi-Trudi, Giambelli, and Lascoux-Pragacz formulas…
The dimer model and dynamical incidence geometry
Anton Izosimov, Pavlo Pylyavskyy
We propose a geometric counterpart of the dimer model on bipartite graphs. A state of our model consists of a choice of a point for each white vertex and hyperplane for each black…
Kirillov-Reshetikhin Dual Equivalence Graphs
Joseph McDonough, Pavlo Pylyavskyy, Shiyun Wang
Let be a tensor product of highest weight modules of corresponding to multiples of fundamental weights (i.e. rectangles). We consider three ways to stratify $…
