Monodromies of singularities of the Hadamard and eñe product

Abstract : We prove that singularities with monodromies are preserved by Hadamard product, and we find an explicit formula for the monodromy of the singularities of the Hadamard product. We find similar formulas for the eñe product whose monodromy is better behaved. With these formulas we give new direct proofs of classical results and prove the invariance of interesting rings of functions by Hadamard multiplication and eñe product.
