The pasting lemma
In topology, the pasting or gluing lemma, and sometimes the gluing rule, is an important result which says that two continuous functions can be "glued together" to create another continuous function. The lemma is implicit in the use of piecewise functions. For example, in the book Topology and Groupoids, where the condition given for the statement below is that and The pasting lemma is crucial to the construction of the fundamental group or fundamental groupo… WebbAnother point is that for vector fields, we can use the pasting lemma for C1 vector fields, since we know that C∞ divergence-free vector fields are dense in C1 divergence-free …
