Abstract

Let XSX \rightarrow S be a smooth projective surjective morphism, where XX and SS are integral schemes over complex numbers. Let L_0, L_1, .... L_{n-1}, L_{n} be line bundles over XX. There is a natural isomorphism of the Deligne pairing <L0,...,Ln><L_{0},...,L_{n}> with the determinant line bundle Det(i=0n(LiOX)){\rm Det}(\otimes_{i=0}^{n} (L_i- {\mathcal O}_{X})).
