WebIn particular, the Perron Frobenius Theorem for nonnegative tensors is related to measuring higher order connectivity in linked objects [5] and hypergraphs [6]. The purpose of this paper is to extend Perron Frobenius Theorem to nonnegative tensors. It is well known that Perron Frobenius Theorem has the following two forms: Theorem 1.1. WebIn this paper we prove Frobenius’ Theorem, which gives a necessary and suﬃcient condition for the answer to be yes. 1. Motivation Consider S2, the unit 2-sphere in R3. At …
