Abstract:
We give a combinatorial proof of the Dedekind–Mertens formula by computing the initial ideal of the content ideal of the product of two generic polynomials. As a side effect we obtain a complete classification of the rank $1$ Cohen–Macaulay modules over the determinantal rings $K[X]/I_2(X)$.References
