TitleEpimorphisms between knot groups and the images of meridians
We determined whether there exists an epimorphism between knot groups which maps a meridian to a meridian, in case of the knots with up to 11 crossings. The twisted Alexander polynomial is a key tool to determine the non-existence of an epimorphism. In this talk, we show some examples of epimorphisms which do not map meridians to meridians.
