BGW.ContinuumTrees.ContourPaperTransfer

Paper contour transfer for rooted measured convergence #

Composition of the contour law convergence with the paper time convention and the divisor of Remark 5.10: convergence of the rescaled paper contour of random plane trees gives convergence of the laws of the rooted measured trees.
