摘要：

Since the work of Qi (2005) and Lim (2005), the study of tensors which regarded as the generalization of matrices, the spectra of tensors (and hypergraphs) and their various applications has attracted much attention and interest.

A hypergrapha is a pair G = (V (G);E(G)), where V (G) is the set of vertices of G and E(G) is a family of non-empty subsets of V (G). In this talk, we introduce some results and problems on nonnegative tensors and hypergraphs, including the primitive tensors, the sharp bounds for the spectral radius nonnegative tensors and hypergraphs, the majorization theorem of k-uniform supertrees and so on.
