反对称形式:论数学物理方程的可积性

Skew-symmetric forms: On integrability of equations of mathematical physics

L. I. Petrova

摘要:

对数学物理方程可积性的研究表明,描述实过程的微分方程在没有附加条件的情况下是不可积的。这是从这些方程导出的函数关系得出的。这样的关系连接状态泛函的微分和反对称形式。这个关系被证明是不相同的,这一事实指出了方程的不可积性。在这种情况下,方程的解是一个泛函,它依赖于看起来不封闭的反对称形式的交换子。然而,在退化变换条件的实现下,从不同的关系,它遵循在某些结构上的相同的。这就指出了广义解的局部可积性和可实现性。在这样做时,除了外部形式,反对称形式,这与外部形式相反,定义在不可积流形(如微分方程的切流形,拉格朗日流形等),被使用。本文分析了描述任意过程的偏微分方程、连续介质的力学和物理微分方程组以及场论方程。

英文摘要:

The study of integrability of the mathematical physics equations showed that the differential equations describing real processes are not integrable without additional conditions. This follows from the functional relation that is derived from these equations. Such a relation connects the differential of state functional and the skew-symmetric form. This relation proves to be nonidentical, and this fact points to the nonintegrability of the equations. In this case a solution to the equations is a functional, which depends on the commutator of skew-symmetric form that appears to be unclosed. However, under realization of the conditions of degenerate transformations, from the nonidentical relation it follows the identical one on some structure. This points out to the local integrability and realization of a generalized solution. In doing so, in addition to the exterior forms, the skew-symmetric forms, which, in contrast to exterior forms, are defined on nonintegrable manifolds (such as tangent manifolds of differential equations, Lagrangian manifolds and so on), were used. In the present paper, the partial differential equations, which describe any processes, the systems of differential equations of mechanics and physics of continuous medium and field theory equations are analyzed.
