Abstract

In this paper, as a generalization to content algebras, we introduce amount algebras. Similar to the Anderson-Badawi ωR[X](I[X])=ωR(I)\omega_{R[X]}(I[X])=\omega_R(I) conjecture, we prove that under some conditions, the formula ωB(Iϵ)=ωR(I)\omega_B(I^{\epsilon})=\omega_R(I) holds for some amount RR-algebras BB and some ideals II of RR, where ωR(I)\omega_R(I) is the smallest positive integer nn that the ideal II of RR is nn-absorbing. A corollary to the mentioned formula is that if, for example, RR is a Pr\"{u}fer domain or a torsion-free valuation ring and II is a radical ideal of RR, then ωR[][X]](I[[X]])=ωR(I)\omega_{R[][X]]}(I[[X]])=\omega_R(I).
