One invariant measure and different Poisson brackets for two nonholonomic systems
arXiv:1106.1952 · doi:10.1134/S1560354712010078
Abstract
We discuss the nonholonomic Chaplygin and the Borisov-Mamaev-Fedorov systems, for which symplectic forms are different deformations of the square root from the corresponding invariant volume form. In both cases second Poisson bivectors are determined by -tensors with non-zero torsion on the configurational space, in contrast with the well known Eisenhart-Benenti and Turiel constructions.
