Shapovalov类波时空

Shapovalov wave-like spacetimes

Konstantin Osetrin, Evgeny Osetrin

摘要:

给出了时空模型的一个完整分类,它允许特权坐标系,其中测试粒子的Hamilton-Jacobi方程通过完全分离变量的方法与各向同性(波)变量的分离来积分,空间的度量依赖于(类波Shapovalov空间)。对于各种类型的Shapovalov空间,求出了真空中含宇宙学常数的Einstein方程的精确解,给出了Eikonal方程和试验粒子的Hamilton-Jacobi运动方程的完全积分.

英文摘要:

A complete classification of space-time models is presented, which admit the privileged coordinate systems, where the Hamilton-Jacobi equation for a test particle is integrated by the method of complete separation of variables with separation of the isotropic (wave) variable, on which the metric of space depends (wave-like Shapovalov spaces). For all types of Shapovalov spaces, exact solutions of the Einstein equations with a cosmological constant in vacuum are found. Complete integrals are presented for the eikonal equation and the Hamilton-Jacobi equation of motion of test particles.
