Abstract

Let RR be a Noetherian ring and x1,,xtx_1,\ldots,x_t a permutable regular sequence of elements in RR. Then there exists a finite set of primes Λ\Lambda and natural number CC so that for all n1,,ntn_1,\ldots,n_t there exists a primary decomposition (x1n1,,xtnt)=Q1Q(x_1^{n_1},\ldots,x_t^{n_t})=Q_1\cap \cdots \cap Q_\ell so that QiΛ\sqrt{Q_i}\in \Lambda and QiC(n1++nt)Qi\sqrt{Q_i}^{C(n_1+\cdots + n_t)}\subseteq Q_i for all 1i1\leq i\leq \ell.
