Computing the norm of nonnegative matrices and the log-Sobolev constant of Markov chains
Antoine Gautier, Matthias Hein, Francesco Tudisco
We analyze the global convergence of the power iterates for the computation of a general mixed-subordinate matrix norm. We prove a new global convergence theorem for a class of ent…
Shifted and extrapolated power methods for tensor -eigenpairs
Stefano Cipolla, Michela Redivo-Zaglia, Francesco Tudisco
This work is concerned with the computation of -eigenvalues and eigenvectors of square tensors with modes. In the first part we propose two possible shifted variants of…
Ergodicity coefficients for higher-order stochastic processes
Dario Fasino, Francesco Tudisco
The use of higher-order stochastic processes such as nonlinear Markov chains or vertex-reinforced random walks is significantly growing in recent years as they are much better at m…
Extrapolation Methods for fixed-point Multilinear PageRank computations
Stefano Cipolla, Michela Redivo-Zaglia, Francesco Tudisco
Nonnegative tensors arise very naturally in many applications that involve large and complex data flows. Due to the relatively small requirement in terms of memory storage and numb…
