Topology of mixed hypersurfaces of cyclic type

Let f(II)(z, (z) over bar) = z(1)(a1+b1)(z) over bar (-b1)(1)z(2) + ... + z(n-1)(an-1+bn-1)(z) over bar (bn-1)(n-1)z(n) + z(n)(an+bn)(z) over bar (-bn-)(n)z(1) be a mixed weighted homogeneous polynomial of cyclic type and g(II)(z) = z(1)(a1)z(2) + ... + z(n-1)(an-1)z(n) + z(n)(an)z(1) be the associated weighted homogeneous polynomial where a(j) >= 1 and b(j) >= 0 for j = 1,,n. We show that two links S-epsilon(2n-1) boolean AND f(II)(-1)(0) and S-epsilon(2n-1) boolean AND g(II)(-1)(0) are diffeomorphic and their Milnor fibrations are isomorphic.
