Michael Entov, Leonid Polterovich, Daniel Rosen
This paper is a fusion of a survey and a research article. We focus on certain rigidity phenomena in function spaces associated to a symplectic manifold. Our starting point is a lo…

Lie quasi-states
Michael Entov, Leonid Polterovich
Lie quasi-states on a real Lie algebra are functionals which are linear on any abelian subalgebra. We show that on the symplectic Lie algebra of rank at least 3 there is only one c…
