Alexander polynomial conjecture for the monodromy of associated surface singularities

From papers

Let C0C_0 and C1C_1 be the curves and let g0g_0 and g1g_1 be the polynomial function germs associated with them. Write V(gj)V(g_j) for the zero locus of gjg_j and let the monodromy of gjg_j act on its Milnor fiber. The Alexander polynomial conjecture. If the Alexander polynomials of C0C_0 and C1C_1 are different, then the Jordan form of the monodromy of g0g_0 is different from that of g1g_1, and therefore the surface germs (V(g0),0)(V(g_0),\mathbf{0}) and (V(g1),0)(V(g_1),\mathbf{0}) have distinct embedded topologies in C3\mathbb{C}^3. This would strengthen the paper's theorem from a μ\mu-Zariski pair to an ordinary Zariski pair, and is stated without necessarily assuming that the singularities of C0C_0 and C1C_1 are Newton non-degenerate.
