Topological pp-adic Simpson correspondence for moduli spaces

Let KK be algebraically closed, let XX be a smooth proper rigid space over KK, and let nn be a positive integer. Write BunGLn,v(K)|\mathscr{B}\hspace{-0.1em}\mathrm{\textit{un}}_{\mathrm{GL}_n,v}(K)| for the set of isomorphism classes of rank-nn vector bundles on XvX_v, endowed with its natural topology, and write HiggsGLn(K)|\mathscr H\hspace{-0.1em}\mathrm{\textit{iggs}}_{\mathrm{GL}_n}(K)| for the set of isomorphism classes of rank-nn Higgs bundles on XeˊtX_{{\operatorname{\acute{e}t}}} with its natural topology. Topological pp-adic Simpson conjecture. The equivalence between vector bundles on XvX_v and Higgs bundles on XeˊtX_{{\operatorname{\acute{e}t}}} induces a homeomorphism

BunGLn,v(K)HiggsGLn(K).|\mathscr{B}\hspace{-0.1em}\mathrm{\textit{un}}_{\mathrm{GL}_n,v}(K)|\xrightarrow{\sim}|\mathscr H\hspace{-0.1em}\mathrm{\textit{iggs}}_{\mathrm{GL}_n}(K)|.

This strengthens the pp-adic Simpson correspondence by requiring compatibility with the natural topologies on the moduli sets, in analogy with the complex Corlette--Simpson correspondence. The supplied text does not state whether this refinement has been proved, so its status remains open here.
