Abstract

It is well known that the diffeomorphism-type of the Milnor fibration of a (Newton) non-degenerate polynomial function ff is uniquely determined by the Newton boundary of ff. In the present paper, we generalize this result to certain degenerate functions, namely we show that the diffeomorphism-type of the Milnor fibration of a (possibly degenerate) polynomial function of the form f=f1fk0f=f^1\cdots f^{k_0} is uniquely determined by the Newton boundaries of f1,,fk0f^1,\ldots, f^{k_0} if {fk1==fkm=0}\{f^{k_1}=\cdots=f^{k_m}=0\} is a non-degenerate complete intersection variety for any k1,,km{1,,k0}k_1,\ldots,k_m\in \{1,\ldots, k_0\}.
