Definition 2.53.

Let (𝕂,𝔐𝕂)(\mathbb{K},\mathfrak{M}_{\mathbb{K}}) be an adelic field, XX a proper variety over 𝕂\mathbb{K} and LΒ―i{\overline{L}}_{i}, i=0,…,di=0,\dots,d, a family of integrable metrized line bundles on XX. Let YY be a dd-dimensional cycle of XX. We say that YY is integrable with respect to LΒ―0,…,LΒ―d{\overline{L}}_{0},\dots,{\overline{L}}_{d} if there is a proper map Ο†:Xβ€²β†’X\varphi\colon X^{\prime}\to X, a cycle Yβ€²Y^{\prime} of Xβ€²X^{\prime} such that Ο†βˆ—β€‹Yβ€²=Y\varphi_{\ast}Y^{\prime}=Y, and rational sections sis_{i} of Ο†βˆ—β€‹Li\varphi^{\ast}L_{i}, i=0,…,di=0,\dots,d, that intersect Yβ€²Y^{\prime} properly and such that for all but a finite number of vβˆˆπ”π•‚v\in\mathfrak{M}_{\mathbb{K}},

(2.54) hv,Ο†Β―βˆ—β€‹L0,…,Ο†Β―βˆ—β€‹Ld⁑(Yβ€²,s0,…,sd)=0,\operatorname{h}_{v,{\overline{\varphi}}^{\ast}L_{0},\dots,{\overline{\varphi}}^{\ast}L_{d}}(Y^{\prime};s_{0},\dots,s_{d})=0,

where hv\operatorname{h}_{v} denotes the local height function on XvX_{v}.
