© 2019 Elsevier B.V. We consider the computation of the matrix logarithm by using numerical quadrature. The efficiency of numerical quadrature depends on the integrand and the choice of quadrature formula. The Gauss–Legendre quadrature has been co...

We present novel geometric numerical integrators for Hunter–Saxton-like equations by means of new multi-symplectic formulations and known Hamiltonian structures of the problems. We consider the Hunter–Saxton equation, the modified Hunter–Saxton eq...

We consider estimation of ordinary differential equation (ODE) models from
noisy observations. For this problem, one conventional approach is to fit
numerical solutions (e.g., Euler, Runge--Kutta) of ODEs to data. However, such
a method does not a...
