Proposition 2.11.

Let K′/KK^{\prime}/K be a finite normal extension and let q:X′:=X⊗KK′→Xq\colon X^{\prime}:=X\otimes_{K}{K^{\prime}}\to X be the natural projection. For θ∈𝒵1,1​(X)\theta\in\mathcal{Z}^{1,1}(X) and u∈C0​(Xan)u\in C^{0}({X^{{\mathrm{an}}}}), we have

(2.5) q∗​(Pθ​(u))=Pq∗​θ​(q∗​(u)).q^{*}(P_{\theta}(u))=P_{q^{*}\theta}(q^{*}(u)).
