Critical length: an alternative approach
Carolina Vittoria Beccari, Giulio Casciola, Marie-Laurence Mazure
We provide a numerical method to determine the critical lengths of linear differential operators with constant real coefficients. The need for such a procedure arises when the orde…

Piecewise Extended Chebyshev Spaces: a numerical test for design
Carolina Vittoria Beccari, Giulio Casciola, Marie-Laurence Mazure
Given a number of Extended Chebyshev (EC) spaces on adjacent intervals, all of the same dimension, we join them via convenient connection matrices without increasing the dimension.…
