Normal covering map
WebIn general, not all covering maps p will be the quotient by the action of a group: this will only be the case for normal covering maps, i.e. those for which p∗(π1(X˜)) is a normal subgroup N; Then π1(X, x0)/N is a group, and this will act in the same way as above, with quotient X. Example 1.39 (Coverings of surfaces).

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
