Title: Eigenvalues of tensors and spectral hypergraph theory

Abstract: We will discuss a notion of eigenvalues/vectors and singular 
values/vectors for tensors of order 3 and higher. To illustrate its 
utility, we show how it may be used to study hypergraphs in a manner akin 
to spectral graph theory. We will also relate the notion to 
hyperdeterminants and tensor norms and prove a Perron-Frobenius theorem 
for irreducible nonnegative tensors.
