Exponential generating functions for trees with weighted edges and labeled nodes
Journal of integer sequences, Tome 10 (2007) no. 8
We study labeled trees and find that this is a class of combinatorial objects which is perfect for the study of some exponential generating functions.
Classification : 05A15
Keywords: labeled tree, Motzkin path, Catalan path, weighted labeled tree, exponential generating function
