The Main Diagonal of a Permutation Matrix
Marko Lindner, Gilbert Strang
By counting 1's in the "right half" of consecutive rows, we locate the main diagonal of any doubly infinite permutation matrix with bandwidth . Then the matrix can be corre…
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 in i…
Condition number estimates for combined potential integral operators in acoustics and their boundary element discretisation
Timo Betcke, Simon N. Chandler-Wilde, Ivan G. Graham +2
We consider the classical coupled, combined-field integral equation formulations for time-harmonic acoustic scattering by a sound soft bounded obstacle. In recent work, we have pro…
Two stable modifications of the finite section method
Marko Lindner
In this article we demonstrate and compare two modified versions of the classical finite section method for band-dominated operators in case the latter is not stable. For both meth…
