Cahiers拓扑中非线性场论的Poisson代数

Poisson algebras for non-linear field theories in the Cahiers topos

Marco Benini, Alexander Schenkel

摘要:

我们开发了一种方法来构建泊松代数的非线性标量场,是基于Cahiers拓扑模型的综合微分几何。在这个框架内的解决方案空间的场方程进行了自然的光滑结构,并按照祖克曼的想法,我们可以赋予它一个presymplectic电流。我们制定的哈密顿向量场方程在这种情况下,并表明,它选择了一个家庭的观测值,形成一个泊松代数。我们的方法提供了一个干净的泊松代数,这是足以保证存在的建设几何和代数方面之间的分裂,和分析方面,是至关重要的分析其属性。

英文摘要:

We develop an approach to construct Poisson algebras for non-linear scalar field theories that is based on the Cahiers topos model for synthetic differential geometry. In this framework the solution space of the field equation carries a natural smooth structure and, following Zuckerman's ideas, we can endow it with a presymplectic current. We formulate the Hamiltonian vector field equation in this setting and show that it selects a family of observables which forms a Poisson algebra. Our approach provides a clean splitting between geometric and algebraic aspects of the construction of a Poisson algebra, which are sufficient to guarantee existence, and analytical aspects that are crucial to analyze its properties.
