The longest increasing subsequences of Luce permutations and permutons

Jacopo Borga, Victor Dubach

We investigate the longest increasing subsequences (LIS) of random permutations distributed under the Luce model with weights $θ_{1}^{(n)} \geq \dots \geq θ_{n}^{(n)}$ . Our first main r…

Limits of descent-biased trees

Victor Dubach, Paul Thévenin, Stephan Wagner

We investigate scaling and local limits of random trees biased according to their number of descents. A descent in a rooted labeled tree $t$ is a parent-child pair such that the la…

Large deviation principles for pattern-avoiding permutations, and limit shapes for constrained Mallows permutations

Thomas Budzinski, Victor Dubach, Valentin Féray +2

We study Mallows random permutations conditioned to avoid a given pattern $α$ of length~ $3$ . When the bias parameter is of the form $e^{β / n}$ , we prove that these permutations conv…
