A general framework for inequalities on simple graphs

Ludovick Bouthat, Ángel Chávez, Sam Sheng

A general framework is developed for deriving sharp inequalities on simple graphs from majorization and Schur-convexity. After establishing majorization relations between the spect…

Number of orbits of $k$ -subsets of permutations

Ludovick Bouthat, Raghavendra Tripathi

Let $S_{n}$ denote the symmetric group of order $n$ . Say that two subsets $x, y \subseteq S_{n}$ are \emph{equivalent} if there exist permutations $g_{1}, g_{2} \in S_{n}$ such that $g_1xg_2=y…
