Fast eight-order Pade schemes based on Chebyshev polynomials for direct Zakharov-Shabat problem

Sergey Medvedev, Igor Chekhovskoy, Irina Vaseva +1

In this work, we construct fast eighth-order Pade schemes for the direct Zakharov-Shabat scattering problem. The schemes are based on an eighth-order exponential integrator obtaine…
