In the proof that covering transformations are covering maps, why is \(q\circ (p_2) _W\) a local inverse for \(F\)? Because I was using the lifting criterion, I should have added an assumption about my spaces in the first theorem.

However, the criterion I came up with and proved seems to be a little bit weaker than what is stated in other textbooks. I don't know ... Webcovering map by construction. We need to show that it is not a normal covering. We know that the fundamental group ˇ 1(K) has the presentation ˇ 1(K) ˘=ha;bjabab 1 = ei since K is built by attaching a 2-cell to the above depicted fundamental polygon. The induced map p: ˇ 1(K) !ˇ 1(K) sends bto itself, but maps ato a3, so the subgroup
