Query: Quasi-morphisms and quasi-states in symplectic topology   This is a survey about certain "almost homomorphisms" and "almost linear"
functionals (called quasi-morphisms and quasi-states) in symplectic topology
and their applications to Hamiltonian dynamics, functional-theoretic properties
of Poisson brackets and algebraic and metric properties of symplectomorphism
groups.
