Flows on graphs with cycles, locally gentle algebras, and the Mutoperhedron

Antoine Abram, Jose Bastidas, Benjamin Dequêne +3

Flow cones of a directed acyclic graph admit a family of unimodular triangulations given by Danilov, Karzanov, and Koshevoy (DKK) whose normal fans are related to (generalizations)…

An extended generalization of RSK correspondence via $A$ type quiver representations

Benjamin Dequêne

Let $λ = (λ_{1} ⩾ \dots ⩾ λ_{k} > 0)$ . For any $c$ Coxeter element of $S_{λ_{1} + k - 1}$ , we construct a bijection from fillings of $λ$ to reverse plane partitions…

An extended generalization of RSK via the combinatorics of type $A$ quiver representations

Benjamin Dequêne

The classical Robinson--Schensted--Knuth correspondence is a bijection from nonnegative integer matrices to pairs of semi-standard Young tableaux. Based on the work of, among other…

Charmed roots and the Kroweras complement

Benjamin Dequêne, Gabriel Frieden, Alessandro Iraci +3

Although both noncrossing partitions and nonnesting partitions are uniformly enumerated for Weyl groups, the exact relationship between these two sets of combinatorial objects rema…
