permuton (plural permutons)

1. (mathematics, physics) A probability measure Φ on the σ-algebra of Borel sets of the unit square [0,1] such that Φ has uniform marginals (that is, Φ ([α, β] × [0,1]) = Φ ([0,1] × [α, β]) = β − α for every 0 ≤ α ≤ β ≤ 1).

     In the recent terminology of permutons, our work can be interpreted as the convergence of uniform random separable permutations towards a "Brownian separable permuton"..
