G-symplecticity implies conjugate-symplecticity of the underlying one-step method
Raffaele D'Ambrosio, Ernst Hairer and Christophe Zbinden
Abstract.
This note proves that the underlying one-step method of
a G-symplectic general linear method is conjugate to
a symplectic method. Parasitic solution components
are not considered.
Key Words.
Multi-value method, G-symplectic, underlying one-step method, conjugate-symplectic.
