Decompletion conjecture for compact p-adic Lie groups

Let GG be a compact pp-adic Lie group, and let MM and the associated period rings and locally analytic-vector functor be as in Theorem 1. The Lie algebra Lie(G)\mathrm{Lie}(G) is not assumed to be abelian. Decompletion conjecture. The statement of Theorem 1 holds for any compact pp-adic Lie group GG (with no assumption on Lie(G)\mathrm{Lie}(G)). This conjecture proposes that the decompletion result extends beyond the Lie-algebra hypothesis used in the theorem.
