The Subtree Size Profile of Plane-oriented Recursive Trees

Abstract: In this extended abstract, we outline how to derive limit theorems for the number of subtrees of size k on the fringe of random plane-oriented recursive trees. Our proofs are based on the method of moments, where a complex-analytic approach is used for constant k and an elementary approach for k which varies with n. Our approach is of some generality and can be applied to other simple classes of increasing trees as well.

“…These include the limit distribution of the normalized profile, asymptotic bimodality of the variance, asymptotic approximation to the expected width and the correlation coefficients of two level sizes. Fuchs [369] outlines how to derive limit theorems for the number of sub-trees of size k on the fringe of random plane-oriented recursive trees. Finally, Janson, Kuba and Panholzer [446] consider generalized Stirling permutations and relate them with certain families of generalized plane recursive trees.…”
