标题： A model of gravitation with global U(1)-symmetry

摘要： 结果显示，将广义相对论的$4-$空间嵌入到平坦的$12-$空间中，可以得到一个具有全局$U(1)-$对称性和离散$D_{1}-$对称性的引力模型。 最后一个可以转化为统一模型的$SU(2)-$对称性，而$U(1)-$和$SU(2)-$变换的独立性要求导致了估计$\sin^{2}\theta_{min}=0,20$，其中$\theta_{min}$是标准模型 Weinberg 角的一个类比。 显示英文摘要

摘要： It is shown that an embedding of the general relativity $4-$space into a flat $12-$space gives a model of gravitation with the global $U(1)-$symmetry and the discrete $D_{1}-$one. The last one may be transformed into the $SU(2)-$symmetry of the unified model, and the demand of independence of $U(1)-$ and $SU(2)-$transformations leads to the estimate $\sin^{2}\theta_{min}=0,20$ where $\theta_{min}$ is an analog of the Weinberg angle of the standard model.
