Extract

An analytic map-germ f:(ℂn, 0)→(ℂp, 0) is said to be quasi-homogeneous, or weighted homogeneous, if there are positive integers w1, …, wn, the weights, and positive integers d1, …, dp, the degrees, such that for each monomial appearing in the Taylor expansion of the ith component fi of f, we have
