4. Similar to homotopy classes, one defines two immersions to be in the same regular homotopy class if there exists a regular homotopy between them.
5. While immersed plane curves, up to regular homotopy, are determined by their turning number, knots have a very rich and complex structure.
6. It's difficult to find regular homotopy in a sentence. 用regular homotopy造句挺难的
