Abstract:Let $ R $ be a regular local ring with maximal ideal $ \mathfrak{m} $. We consider elements $ f \in R $ such that their Newton polyhedron has a loose edge. We show that if the symbolic restriction of $ f$ to such an edge is a product of two coprime polynomials, then $ f$ factorizes in the $ \mathfrak{m} $-adic completion.

边缘松散和因式分解定理

摘要:让$ R $具有最大理想的规则局部环成为可能。我们考虑这样的元素,使它们的牛顿多面体具有宽松的边缘。我们证明,如果对这样的边缘的符号限制是两个互质多项式的乘积,则将-adic补全分解。 $ \ mathfrak {m} $$ f \在R $$ f $$ f $ $ \ mathfrak {m} $
