Abstract:

For each integer $n\ge 2$ we construct a compact, geodesic metric space $X$ which has topological dimension $n$, is Ahlfors $n$-regular, satisfies the Poincaré inequality, possesses $\mathbb R^n$ as a unique tangent cone at $\mathcal {H}_n$ almost every point, but has no manifold points.
