摘要

在几何量子化的背景下，我们将任何前量子束自形化与相应量子空间的单元映射联系起来。在半经典极限中，这些映射受控于交映拓扑学的两个不变式：卡拉比-韦恩斯坦变形和恩托夫、派、谢卢欣引入的汉密尔顿衍射群普遍盖上的准变形。

On a quasimorphism of Hamiltonian diffeomorphisms and quantization

In the setting of geometric quantization, we associate to any prequantum bundle automorphism a unitary map of the corresponding quantum space. These maps are controlled in the semiclassical limit by two invariants of symplectic topology: the Calabi–Weinstein morphism and a quasimorphism on the universal cover of the Hamiltonian diffeomorphism group introduced by Entov, Py, Shelukhin.

期刊介绍： Publishes high quality papers on all aspects of symplectic geometry, with its deep roots in mathematics, going back to Huygens’ study of optics and to the Hamilton Jacobi formulation of mechanics. Nearly all branches of mathematics are treated, including many parts of dynamical systems, representation theory, combinatorics, packing problems, algebraic geometry, and differential topology.
