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…

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…

A variation of Broyden Class methods using Householder adaptive transforms
S. Cipolla, C. Di Fiore, P. Zellini
In this work we introduce and study novel Quasi Newton minimization methods based on a Hessian approximation Broyden Class-\textit{type} updating scheme, where a suitable matrix $\…
