Proposition 1.3.2.

Let φ\varphi be a smooth function on X\mathrm{X} and let L¯1,…,L¯k\overline{L}_{1},\dots,\overline{L}_{k} be admissible metrized line bundles ; let Z\mathrm{Z} be a kk-dimensional subvariety of X\mathrm{X} and let ss be an invertible meromorphic sections of L¯1\overline{L}_{1}. Then,

∫Xφ​c1​(L¯1)​…​c1​(L¯k)​δZ=∫Xφ​c1​(L¯2)​…​c1​(L¯k)​δdiv⁡(s|Z)+∫Xlog⁡‖s‖−1​ddc⁡φ​c1​(L¯2)​…​c1​(L¯k)​δZ.\int_{\mathrm{X}}\varphi c_{1}(\overline{L}_{1})\dots c_{1}(\overline{L}_{k})\delta_{\mathrm{Z}}\\ =\int_{\mathrm{X}}\varphi c_{1}(\overline{L}_{2})\dots c_{1}(\overline{L}_{k})\delta_{\operatorname{div}(s|\mathrm{Z})}+\int_{X}\log\left\|{s}\right\|^{-1}\mathop{\mathrm{d}\mathrm{d}^{c}}\varphi c_{1}(\overline{L}_{2})\dots c_{1}(\overline{L}_{k})\delta_{\mathrm{Z}}.
