The images on this page are taken from this work on meanders and this work on meandric systems. Meanders and meandric permutations Left: Two large uniform meanders of size 256 and 2048. Right: The plots of the two corresponding meandric permutations. These simulations are obtained using this paper‘s Markov chain Monte Carlo algorithm. Meandric systems Simulation of a uniform …

The length of the longest increasing subsequence in a random permutation and the size of the largest homogeneous set (i.e. a clique or an independent set) in a random graph are two of the classical problems at the interface of combinatorics and probability theory, with connections to several other areas of mathematics. In this paper, …

The skew Brownian permuton is a universal family of limiting permutons introduced in this work. Here we collect some simulations of the skew Brownian permuton for different values of the parameters and . In every row there are five simulations of and at the end there is the corresponding two-dimensional Brownian excursion of correlation in the non-negative …
The following images were realized during the preparation of the article “Scaling and local limits of Baxter permutations and bipolar orientations through coalescent-walk processes”. Here you can see two uniform large Baxter permutations. We showed that they converge (in the permuton sense) to the Baxter permuton, that is a random probability measure of the unit …
