I. V. Shirokov

AI总结:

研究齐性空间上拉普拉斯算子的调和变量,通过引入其定义,可构建特定非线性微分方程解,针对具有双不变度量的李群和特定齐性空间给出构建算法。

AI中文摘要:

介绍了黎曼和伪黎曼空间上拉普拉斯算子调和变量的定义。调和变量尤其能构建一类非线性微分方程的特定(非不变群)解。对于具有双不变度量的李群和某类齐性空间(如对称空间),给出了构建此类变量的算法。

英文摘要:

A definition of harmonic variables for Laplace operators on Riemannian and pseudo-Riemannian spaces is introduced. Harmonic variables allow, in particular, the construction of particular (non-invariant group) solutions to a wide class of nonlinear differential equations. For Lie groups with a bi-invariant metric and a certain class of homogeneous spaces (e.g., symmetric spaces), an algorithm for constructing such variables is presented.
