Low-rank approximation in the numerical modeling of the Farley-Buneman instability in ionospheric plasma
S. V. Dolgov, A. P. Smirnov, E. E. Tyrtyshnikov
We consider the numerical modeling of the Farley-Buneman instability development in the earth's ionosphere plasma. The ion behavior is governed by the kinetic Landau equation in th…

Optimal rank matrix algebras preconditioners
F. Tudisco, C. Di Fiore, E. E. Tyrtyshnikov
When a linear system Ax = y is solved by means of iterative methods (mainly CG and GMRES) and the convergence rate is slow, one may consider a preconditioner P. The use of such pre…
