Invariant measures as obstructions to attractors in dynamical systems and their role in nonholonomic mechanics
L. C. GarcÃa-Naranjo, R. Ortega, A. J. Ureña
We present some rigorous results on the absence of a wide class of invariant measures for dynamical systems possessing attractors. We then consider a generalization of the classica…
