Abstract:

According to the nonnegative tensors defined in Xu et al. (2016), we first obtain some combinatorial identities related on these tensors. Then we attain a sharp upper bound on the spectral radius of this type tensors and its corresponding extremal conditions by these combinatorial identities. As its applications, some sharp upper bounds on the spectral radius of general hypergraphs are deduced and their corresponding extremal structure are characterized.

Key words: nonnegative general-tensor, weakly irreducibletensor, spectral radius
