TITRE / TITLE
Impossibility results in Mathematics
R脡SUM脡 / ABSTRACT
Impossibility results have played an important role in mathematics, from questions like solutions of polynomials, the word problem in group theory to non-measurable subsets of [0, 1]. This talk will present new impossibility results about classical problems in dynamical systems and ergodic theory. They answer questions dating to Poincar茅 and others asked by von Neumann and Smale.
