On the extreme eigenvalues and asymptotic conditioning of a class of Toeplitz matrix-sequences arising from fractional problems
M. Bogoya, S. M. Grudsky, M. Mazza +1
The analysis of the spectral features of a Toeplitz matrix-sequence , generated by a symbol , real-valued almost everywhe…
Asymptotic spectra of large (grid) graphs with a uniform local structure (part II): numerical applications
Andrea Adriani, Davide Bianchi, Paola Ferrari +1
In the current work we are concerned with sequences of graphs having a grid geometry, with a uniform local structure in a bounded domain , . When $Ω…
Spectral and norm estimates for matrix sequences arising from a finite difference approximation of elliptic operators
Armando Coco, Sven-Erik Ekström, Giovanni Russo +2
When approximating elliptic problems by using specialized approximation techniques, we obtain large structured matrices whose analysis provides information on the stability of the…
A matrix-theoretic spectral analysis of incompressible Navier-Stokes staggered DG approximation and related solvers
Mariarosa Mazza, Matteo Semplice, Stefano Serra-Capizzano +1
The incompressible Navier-Stokes equations are solved in a channel, using a Discontinuous Galerkin method over staggered grids. The resulting linear systems are studied both in ter…
