Limiting Probabilities for Vertices of a Given Rank in 1-2 Trees

“…However, for our non-plane 1-2 trees, the sum turns out to be 1, although not in a trivial way. This is the content of the following Theorem that has been conjectured by the present authors, and has recently been proved by Svante Janson [9]. In order to prove Theorem 2.9, we first need the following fact.…”

A multilinear algebra proof of the Cauchy–Binet formula and a multilinear version of Parsevalʼs identity

“…I thank Svante Janson [10] for pointing out reference [9] to me and for his comments on this article, and Richard Ehrenborg [4] for kindly making his notes available to me.…”
