Hilbert流形上的坐标形式

Coordinate formalism on Hilbert manifolds

Alexey A. Kryukov

摘要:

无限维流形上的任意希尔伯特空间的功能被认为是仿照。它表明,在模型的变化,而不是在同一个模型中的图表的变化,使有限维和无限维流形上的坐标形式主义非常相似。在这种情况下,所获得的无限维对应的简单的概念,如基础,对偶基础,正交基础等被证明是密切相关的模型的选择。它还表明,在这种形式主义的一个单一的张量方程的无限维流形上产生一个家庭的功能方程的不同空间的功能。

英文摘要:

Infinite-dimensional manifolds modelled on arbitrary Hilbert spaces of functions are considered. It is shown that changes in model rather than changes of charts within the same model make coordinate formalisms on finite and infinite-dimensional manifolds deeply similar. In this context the obtained infinite-dimensional counterparts of simple notions such as basis, dual basis, orthogonal basis, etc. are shown to be closely related to the choice of a model. It is also shown that in this formalism a single tensor equation on an infinite-dimensional manifold produces a family of functional equations on different spaces of functions.
