Description
In the literature, the domain wall is usually connected with some discrete symmetry. For the continuous case, a discrete symmetry arises as an intermediate stage, but what if the scale of the U(1) symmetry is similar or lower with the ``discrete symmetry''? We show how the domain wall disappear and the discrete symmetry becomes invalid.
