摘要
Let I be an ideal of a polynomial algebra over a field generated by r square free monomials of degree d. If r is bigger than (or equal to, if I is not principal) the number of square free monomials of I of degree d + 1, then depth I-S = d. Let J subset of I, J not equal 0 be generated by square free monomials of degree = d + 1. If r is bigger than the number of square free monomials of I\J of degree d + 1 or, more generally, the Stanley depth of I/J is d, then depth I-S/J = d. In particular, Stanley's Conjecture holds in these cases.
