Energy-Preserving Integrators Applied to Nonholonomic Systems [PDF]
Journal of Nonlinear Science, 2019 We introduce energy-preserving integrators for nonholonomic mechanical systems. We will see that the nonholonomic dynamics is completely determined by a triple $({\mathcal D}^*, Π, \mathcal{H})$, where ${\mathcal D}^*$ is the dual of the vector bundle determined by the nonholonomic constraints, $Π$ is an almost-Poisson bracket (the nonholonomic bracket)
