Analysis of the spectral symbol associated to discretization schemes of linear self-adjoint differential operators
Davide Bianchi
Given a linear self-adjoint differential operator along with a discretization scheme (like Finite Differences, Finite Elements, Galerkin Isogeometric Analysis, etc.),…

Generalized Structure Preserving Preconditioners for Frame-Based Image Deblurring
Davide Bianchi, Alessandro Buccini
We are interested in fast and stable iterative regularization methods for image deblurring problems with space invariant blur. The associated coefficient matrix has a Block Toeplit…

Asymptotic spectra of large (grid) graphs with a uniform local structure
Andrea Adriani, Davide Bianchi, Stefano Serra-Capizzano
We are concerned with sequences of graphs having a grid geometry, with a uniform local structure in a bounded domain , . We assume to be Lebesgu…
