Yet another generalization of Postnikov's hook length formula for binary trees

Combinatorics 2008-04-29 v1

Abstract

We discover another one-parameter generalization of Postnikov's hook length formula for binary trees. The particularity of our formula is that the hook length hvh_v appears as an exponent. As an application, we derive another simple hook length formula for binary trees when the underlying parameter takes the value 1/2.
