Abstract

A torus-covering T2T^2-knot is a surface-knot of genus one determined from a pair of commutative braids. For a torus-covering T2T^2-knot FF, we determine the number of irreducible metabelian SU(2)SU(2)-representations of the knot group of FF in terms of the knot determinant of FF. It is similar to the result due to Lin for the knot group of a classical knot. Further, we investigate the number of irreducible metabelian SU(2)SU(2)-representations using Fox's pp-colorability.
