Extremal $k$ -forcing sets in oriented graphs

Yair Caro, Randy Davila, Ryan Pepper

This article studies the \emph{ $k$ -forcing number} for oriented graphs, generalizing both the \emph{zero forcing number} for directed graphs and the $k$ -forcing number for simple g…

Polytopal realizations of finite type $g$ -vector fans

Christophe Hohlweg, Vincent Pilaud, Salvatore Stella

This paper shows the polytopality of any finite type $g$ -vector fan, acyclic or not. In fact, for any finite Dynkin type $Γ$ , we construct a universal associahedron $\math…
