Proposition 2.11 .
Let K ′ / K K^{\prime}/K be a finite normal extension and let q : X ′ := X ⊗ K K ′ → X q\colon X^{\prime}:=X\otimes_{K}{K^{\prime}}\to X be the natural projection.
For θ ∈ 𝒵 1 , 1 ( X ) \theta\in\mathcal{Z}^{1,1}(X) and u ∈ C 0 ( X an ) u\in C^{0}({X^{{\mathrm{an}}}}) ,
we have
(2.5)
q ∗ ( P θ ( u ) ) = P q ∗ θ ( q ∗ ( u ) ) . q^{*}(P_{\theta}(u))=P_{q^{*}\theta}(q^{*}(u)).
