 The eigenvalue problem of nonnegative tensors has applications in 
  
 multi-linear pagerank, spectral hypergraph theory and higher-order 
  
 Markov chains, etc. The eigenvalue problem of general or 
  
 symmetric tensors is in general NP-hard. On the other hand, 
  
 recently, it was discovered that the largest eigenvalue problem of a 
  
 nonnegative tensor has linearly convergent algorithms. This research 
  
 topic attracted much attention. In the world, now there are at 
  
 least ten research teams at USA, France, Italy, Australia, Mainland 
  
 China and Hong Kong, working on this topic. On December 18, 2010, 
  
 we held a workshop on eigenvalues of nonnegative tensors. 
  
 After this workshop, there are further developments on the nonnegative 
  
 tensor models for higher-order Markov chains. This talk gives a survey 
  
 on the developments on this topic.
