这是关于辛拓扑中某些“几乎同态”和“几乎线性”泛函(称为拟态射和拟态)及其在哈密顿动力学、泊松括号的泛函理论性质以及辛同态群的代数和度量性质中的应用的调查。
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.
