Sparse optimization for estimating the cross-power spectrum in linear inverse models : from theory to the application in brain connectivity
Laura Carini, Isabella Furci, Sara Sommariva
In this work we present a computationally efficient linear optimization approach for estimating the cross--power spectrum of an hidden multivariate stochastic process from that of…
Block structured matrix-sequences and their spectral and singular value canonical distributions: a general theory
Isabella Furci, Andrea Adriani, Stefano Serra-Capizzano
In recent years more and more involved block structures appeared in the literature in the context of numerical approximations of complex infinite dimensional operators modeling rea…
Analysis on aggregation and block smoothers in multigrid methods for block Toeplitz linear systems
Matthias Bolten, Marco Donatelli, Paola Ferrari +1
We present novel improvements in the context of symbol-based multigrid procedures for solving large block structured linear systems. We study the application of an aggregation-base…
Flipped structured matrix-sequences in image deblurring with general boundary conditions
Paola Ferrari, Isabella Furci, Stefano Serra-Capizzano
Motivated by a recent work on a preconditioned MINRES for flipped linear systems in imaging, in this note we extend the scope of that research for including more precise boundary c…
