Hilbert's Fifth Problem and the Hilbert–Smith Conjecture

Equivalent p-adic formulation: the p-adic integers ℤ_[p] cannot act continuously and faithfully on any connected finite-dimensional topological manifold. By the Gleason–Yamabe theorem, this is equivalent to hilbert_smith_conjecture.

Statement artifacts, not proofs

These records expose exact Lean propositions and statement-only wrappers. Defining a proposition does not supply a proof of it. A placeholder-bearing target also contains no proof. Elaboration checks syntax and types; it does not certify that a formalization perfectly captures every nuance of the informal problem.
