We prove that the twisted Alexander polynomial of a torus knot with
an irreducible SL(2,C)-representation is locally constant. In the case of a (2, q)
torus knot, we can give an explicit formula for the twisted Alexander polynomial
and deduce Hirasawa-Murasugi’s formula for the total twisted Alexander polynomial.
We also give examples which address a mis-statement in a paper of Silver
and Williams.
