WebMar 1, 1990 · Pasting is the fundamental operation within a 2-category. However, until recently, it had never been proved that the operation of pasting is well defined. In fact, a 2-categorical pasting theorem had not even been properly formulated. Herein, we state and prove such a result. WebThe Pasting Lemma provides us with a new way to create continuous function on a larger domain. It is an important result in topology, and it is very useful. The following discourse is an application of the Pasting Lemma in algebraic topology. De nition. Let X Rn be a subset of the Euclidean n-space. A path in X is a continuous function: [0;1 ...

The idea behind proofs that use the pumping lemma is as follows. To prove a given language L is nonregular, by way of contradiction, assume that L is regular. Then there must be a machine on n states accepting L, for some positive integer n.
