Abstract
Adopting Bażański’s action, two new classes of path equations are derived in Einstein’s nonsymmetric geometry. The first class is the path equations of a test particle moving in a gravitational field, while the second class represents path equations of charged particles. The quantum features of this geometry appear in both classes. The path equations of charged particles give rise to the Lorentz force. Moreover, these path equations may represent an interpretation of some interactions between torsion and the electromagnetic potential even if the electromagnetic force vanishes. It is to be noted that the above two classes of paths are formulated in terms of Einstein’s n onsymmetric connection. An explicit formula of such a connection, satisfying the Einstein metricity condition, is obtained by localizing the global formula given recently by Ivanov and Zlatanović.
采用巴扎斯基的作用,在爱因斯坦的非对称几何中导出了两类新的路径方程。第一类是测试粒子在引力场中运动的路径方程,第二类是带电粒子的路径方程。这两类几何的量子特征都会出现。带电粒子的路径方程产生了洛伦兹力。此外,即使电磁力消失,这些路径方程也可以解释扭转与电磁势之间的某些相互作用。需要指出的是,上述两类路径是根据爱因斯坦的 n 对称连接来表述的。通过将伊万诺夫和兹拉塔诺维奇最近给出的全局公式本地化,可以得到满足爱因斯坦度量条件的这种连接的明确公式。
期刊介绍:
Gravitation and Cosmology is a peer-reviewed periodical, dealing with the full range of topics of gravitational physics and relativistic cosmology and published under the auspices of the Russian Gravitation Society and Peoples’ Friendship University of Russia. The journal publishes research papers, review articles and brief communications on the following fields: theoretical (classical and quantum) gravitation; relativistic astrophysics and cosmology, exact solutions and modern mathematical methods in gravitation and cosmology, including Lie groups, geometry and topology; unification theories including gravitation; fundamental physical constants and their possible variations; fundamental gravity experiments on Earth and in space; related topics. It also publishes selected old papers which have not lost their topicality but were previously published only in Russian and were not available to the worldwide research community
