Pasting Lemma

  Pasting Lemma   M.Velrajan How to learn pure Mathematics by raising questions and by Mathematical Thinking has been illustrated in the following earlier posts in this blogspot.  https://velrajanm.blogspot.com/2024/02/a-way-of-learning-mathematics.html https://velrajanm.blogspot.com/2024/02/view-differently-enjoy-pure-maths-m.html https://velrajanm.blogspot.com/2024/04/learn-enjoy.html https://velrajanm.blogspot.com/2024/04/err-is-human.html https://velrajanm.blogspot.com/2024/06/real-space-to-metric-space-and-normed.html https://velrajanm.blogspot.com/2024/06/significance-of-sequence-1n.html https://velrajanm.blogspot.com/2024/09/graph-of-continuous-functions-real.html In continuation with that in this we learn the Pasting Lemma in Topology. The way of thinking, questions that have to arise and applying the known  concepts are typed in blue colour . For convenience the proof of Pasting Lemma given in Topology by Munkres is given below :  Pasting Lemma ...
