Figure 1From: The Stenger conjectures and the A-stability of collocation Runge-Kutta methodsOrder-star configuration of Legendre (top left), Chebyshev first kind (top right), Chebyshev second kind (bottom left), and Gegenbauer with \(\mu = 1.4\) (bottom right) collocation Runge–Kutta methods for \(n=5\). The configurations show the A-stability of the methodsBack to article page
