Multiplicity bound from containment of powers

At least 16 years old · documented by

Suppose that a\mathfrak{a} and JJ are m\mathfrak{m}-primary ideals in a dd-dimensional Noetherian local or Noetherian graded kk-algebra (R,m)(R,\mathfrak{m}), where kk is a field of arbitrary characteristic. Assume that JJ is generated by a full system of parameters, homogeneous in the graded case. Multiplicity-containment conjecture. If N≥0N\geq 0 and

aN+1⊆J,\mathfrak{a}^{N+1}\subseteq J,

then

e(a)≥(dd+N)de(J).e(\mathfrak{a})\geq\left(\frac{d}{d+N}\right)^d e(J).

This characteristic-independent problem was raised in HMTW and is stated in the paper as a conjecture; the paper notes that it would imply the preceding F-threshold multiplicity conjecture. No resolution is supplied.
