We place ourselves in the situation discussed in the last section, now following [43] closely. We consider a regular sequence F 0,…, Fn of homogeneous polynomials in A[T] = A[T 0,…,Tn ] of positive degrees δ 0,…,δn over a noetherian ring A and the A-algebra C = A[t]/(F 0,…,Fn ). Using the homogeneous ideal t(C) of inertia forms, we define the graded residue class algebra C ¯ ≔ C / T ( C ) https://s3-euw1-ap-pe-df-pch-content-public-u.s3.eu-west-1.amazonaws.com/9780429064265/c3969f1f-00ca-4e1d-a8e4-12dce1f567fb/content/unequ13_105_1.tif"/> which has the same projective spectrum as C. The weights of the indeterminates T 0,…,Tn are γ0,…,γ n . Then the socle determinant Δ = Δ F T https://s3-euw1-ap-pe-df-pch-content-public-u.s3.eu-west-1.amazonaws.com/9780429064265/c3969f1f-00ca-4e1d-a8e4-12dce1f567fb/content/inequ13_105_1.tif"/> belongs to Cσ , σ = ∑ j = 0 n δ j − ∑ i = 0 n γ i https://s3-euw1-ap-pe-df-pch-content-public-u.s3.eu-west-1.amazonaws.com/9780429064265/c3969f1f-00ca-4e1d-a8e4-12dce1f567fb/content/inequ13_105_2.tif"/> , cf.
