Degree distribution in the lower levels of the uniform recursive tree

Probability 2011-12-07 v1

Abstract

In this note we consider the kkth level of the uniform random recursive tree after nn steps, and prove that the proportion of nodes with degree greater than tlognt\log n converges to (1t)k(1-t)^k almost surely, as nn\to\infty, for every t(0,1)t\in(0,1). In addition, we show that the number of degree dd nodes in the first level is asymptotically Poisson distributed with mean 1; moreover, they are asymptotically independent for d=1,2,...d=1,2,....
