A Herglotz-based integrator for nonholonomic mechanical systems
Elias Maciel, Inocencio Ortiz, Christian E. Schaerer
We propose a numerical scheme for the time-integration of nonholonomic mechanical systems, both conservative and nonconservative. The scheme is obtained by simultaneously discretiz…

Morita equivalence of formal Poisson structures
Henrique Bursztyn, Inocencio Ortiz, Stefan Waldmann
We extend the notion of Morita equivalence of Poisson manifolds to the setting of {\em formal} Poisson structures, i.e., formal power series of bivector fields $π=π_0 + λπ_1 +\cdot…
