An inverse free parallel spectral divide and conquer algorithm for nonsymmetric eigenproblems. (English) Zbl 0876.65021

Basically theoretical paper on the subject to determine the eigenvalues of a nonsymmetric matrix \(A\) or of the generalized problem \(A-\lambda B\). An algorithm without matrix inversion is presented, analyzed and compared to other algorithms. Unfortunately there are no numerical experiments on parallel computers.
