Time-symmetry, symplecticity and stability of Euler-Maclaurin and Lanczos-Dyche integration
Charalampos M. Markakis, Michael F. O'Boyle, Derek Glennon +5
Numerical evolution of time-dependent differential equations via explicit Runge-Kutta or Taylor methods typically fails to preserve symmetries of a system. It is known that there e…
