On uniformly continuous function space U(G), Equivalence of invariant mean and topologicalinvariant mean is showed by two methods.
设G为局部紧群，在一致连续函数空间U（ G）上，用两种方法证明左不变平均和拓扑左不变的等价性。

The topological properties for translation, rotation and scale is invariant pattern recognition.
拓扑性质具有对图形的平移、伸缩、旋转的不变性。

A novel topological map is proposed in this paper, and its nodes are represented with the visual scale-invariant features and the beam features of the laser range finder.
