Proof.

Starting with the continuous map in Lemma 3.19, we can determine the pre-image of 𝔐(V^∙(L,⦀⋅⦀))\mathfrak{M}(\widehat{V}_{{\scriptscriptstyle\bullet}}(L,\vvvert\mathord{\cdot}\vvvert)): let z∈(Spec⁡V∙​(L))an∖𝟎anz\in(\spec V_{{\scriptscriptstyle\bullet}}(L))^{\mathrm{an}}\setminus\boldsymbol{0}^{\mathrm{an}} be a point and (x,e∨​(x))(x,e^{\vee}(x)) be its unique pre-image under p​(𝟎)anp(\boldsymbol{0})^{\mathrm{an}}, where x∈Xanx\in X^{\mathrm{an}} and e∨​(x)∈L∨​(x)e^{\vee}(x)\in L^{\vee}(x). By Lemma 3, if we fix a non-zero element e1​(x)∈L​(x)e_{1}(x)\in L(x), the point zz lies in 𝔐(V^∙(L,⦀⋅⦀))\mathfrak{M}(\widehat{V}_{{\scriptscriptstyle\bullet}}(L,\vvvert\mathord{\cdot}\vvvert)) if and only if

|e1(x)|z≤|e1(x)|𝒫(⦀⋅⦀)(x).\lvert e_{1}(x)\rvert_{z}\leq\lvert e_{1}(x)\rvert_{\mathcal{P}(\vvvert\mathord{\cdot}\vvvert)}(x).

This condition is equivalent to

|e∨(e1)(x)|≤|e1(x)|𝒫(⦀⋅⦀)(x).\lvert e^{\vee}(e_{1})(x)\rvert\leq\lvert e_{1}(x)\rvert_{\mathcal{P}(\vvvert\mathord{\cdot}\vvvert)}(x).

Hence there exists a continuous surjective map

p(𝟎)an:𝔻¯∨(L,𝒫(⦀⋅⦀),0)→(𝔐(V^∙(L,⦀⋅⦀))).p(\boldsymbol{0})^{\mathrm{an}}:\overline{\mathbb{D}}^{\vee}(L,\mathcal{P}(\vvvert\mathord{\cdot}\vvvert),0)\rightarrow(\mathfrak{M}(\widehat{V}_{{\scriptscriptstyle\bullet}}(L,\vvvert\mathord{\cdot}\vvvert))).

If we remove 𝕆an\mathbb{O}^{\mathrm{an}} and 𝟎an\boldsymbol{0}^{\mathrm{an}} from the domain and image, the restricted map is indeed a homeomorphism. ∎
