Condition numbers of block Toeplitz matrices and stability of space-time IgA approximations for the wave and Schrödinger equations

Manuel Bogoya, Albrecht Böttcher, Matteo Ferrari +2

In previous work by several authors, the behavior of the condition numbers of banded Toeplitz matrices was studied as the matrix size tends to infinity. In the present contribution…
