High-order Gauss-Legendre methods admit a composition representation and a conjugate-symplectic counterpart
Felice Iavernaro, Francesca Mazzia, Ernst Hairer
One of the most classical pairs of symplectic and conjugate-symplectic schemes is given by the Midpoint method (the Gauss-Runge-Kutta method of order 2) and the Trapezoidal rule. T…

Does the fluid-static equilibrium of a self-gravitating isothermal sphere of van der Waals' gas present multiple solutions?
Domenico Giordano, Pierluigi Amodio, Felice Iavernaro +1
We take up the investigation we left in the future-work stack in Giordano \textit{et al.} [``Fluid statics of a self-gravitational isothermal sphere of van der Waals' gas,'' Phys.…
