Finite sections of random Jacobi operators

Marko Lindner, Steffen Roch

This article is about a problem in the numerical analysis of random operators. We study a version of the finite section method for the approximate solution of equations $A x = b$ in i…

Finite sections of band-dominated operators on discrete groups

V. S. Rabinovich, S. Roch

Let $Γ$ be a finitely generated discrete exact group. We consider operators on $l^{2} (Γ)$ which are composed by operators of multiplication by a function in $l^{\infty} (Γ)$ and by the…
