In this paper, we introduced three uniformities , and which are induced in a natural way on a strongly topological gyrogroup . It is mainly proved that (1) each of the three uniformities is compatible with G; (2) if H is a subgyrogroup of G, then , and ; (3) if is a family of strongly topological gyrogroups, then and , where endowed with the Tychonoff product topology. At the end section, we obtain that every compact strongly topological gyrogroup has property U and every Lindelöf strongly topological gyrogroup has property ω-U.

强拓扑陀螺群的一致性
在本文中,我们介绍了三种均匀性 , 和 在强拓扑陀螺群上以自然方式诱导 . 主要证明了 (1) 三个均匀性中的每一个都与G相容;(2) 若H是G 的一个子陀螺群,则, 和 ; (3) 如果 是一个强拓扑陀螺群族,那么 和 , 在哪里 具有 Tychonoff 积拓扑结构。在最后部分,我们得到每个紧致强拓扑陀螺群都有性质U,每个 Lindelöf 强拓扑陀螺群都有性质ω - U。
