在拓扑学中,一个杯子和一个面包圈(实心环面)是相同的

在数学里,拓扑学英语:topology),或意译为位相几何学,是一门研究拓扑空间的学科,主要研究空间内,在连续变化(如拉伸或弯曲,但不包括撕开或黏合)下维持不变的性质。在拓扑学里,重要的拓扑性质包括连通性与紧致性。

拓扑学是由几何学与集合论里发展出来的学科,研究空间、维度与变换等概念。这些词汇的来源可追溯至哥特佛莱德·莱布尼兹,他在17世纪提出「位置的几何学」(geometria situs)和「位相分析」(analysis situs)的说法。李昂哈德·欧拉的柯尼斯堡七桥问题与欧拉示性数被认为是该领域最初的定理。「拓扑学」一词由利斯廷于19世纪提出,虽然直到20世纪初,拓扑空间的概念才开始发展起来。到了20世纪中叶,拓扑学已成为数学的一大分支。

A continuous deformation (a type of homeomorphism) of a mug into a doughnut (torus) and back

In mathematics, topology (from the Greek τόπος, place, and λόγος, study) is concerned with the properties of space that are preserved under continuous deformations, such as stretching and bending, but not tearing or gluing. This can be studied by considering a collection of subsets, called open sets, that satisfy certain properties, turning the given set into what is known as a topological space. Important topological properties include connectedness and compactness.
