Theorem 2.5.1.

Let L1,…,LnL_{1},\dots,L_{n} be line bundles on X\mathrm{X}. The canonical measure c1​(L¯1)​…​c1​(L¯n)c_{1}(\overline{L}_{1})\dots c_{1}(\overline{L}_{n}) is the direct image by ι\iota of the unique Haar measure on 𝐑t/Λ{\mathbf{R}}^{t}/\Lambda whose total mass is deg⁡(L1​…​Ln)\deg(L_{1}\dots L_{n}).
