We consider formal power series in several variables with coefficients in
arbitrary field such that their Newton polyhedron has a loose edge. We show
that if the symbolic restriction of the power series $f$ to such an edge is a
product of two coprime polynomials, then $f$ factorizes in the ring of power
series. 查看全文>>
