A novel efficient structure-preserving exponential integrator for Hamiltonian systems

Pan Zhang, Fengyang Xiao, Lu Li

We propose a linearly implicit structure-preserving numerical method for semilinear Hamiltonian systems with polynomial nonlinearities, combining Kahan's method and exponential int…
