摘要：

We investigate the profile of random Polya trees of size n when only nodes of degree d are counted in each level. It is shown that, as in the case where all nodes contribute to the profile, the suitably normalized profile process converges weakly to a Brownian excursion local time. Moreover, we investigate the joint distribution of the number of nodes of degrees d(1) and d(2) on the same level of the tree. (C) 2012 Elsevier Inc. All rights reserved.
