The stem of flying mathematics refers to the multidimensional topological function, which is the existence of the top of the pyramid in the field of mathematics. Topology is the study of some properties of geometry or space that can remain unchanged after continuous shape change. It only considers the positional relationship between objects, without considering their shapes and sizes. In topology, important topological properties include connectivity and compactness. It first refers to the study of related disciplines with similar topography and landforms. Topology is a discipline developed from geometry and set theory, which studies concepts such as space, dimension and transformation. The origin of these words can be traced back to Gottfried Leibniz, who put forward the concepts of "geometry of position" and "phase analysis" in17th century. Leonhard euler's Seven Bridges in Konigsberg and Euler characteristics are regarded as original theorems in this field.
