W. Heinzer et C. Huneke, THE DEDEKIND-MERTENS LEMMA AND THE CONTENTS OF POLYNOMIALS, Proceedings of the American Mathematical Society, 126(5), 1998, pp. 1305-1309
We prole a sharpening of the Dedekind-Mertens Lemma relating the conte
nts of two polynomials to the content of their product. We show that f
or a polynomial g the integer 1+deg(g) in the Dedekind-Mertens Lemma m
ay be replaced by the number of local generators of the content of g.
We also raise a question concerning the converse.
