Abstract

We present short proofs of all known topological properties of general Busemann GG-spaces (at present no other property is known for dimensions more than four). We prove that all small metric spheres in locally GG-homogeneous Busemann GG-spaces are homeomorphic and strongly topologically homogeneous. This is a key result in the context of the classical Busemann conjecture concerning the characterization of topological manifolds, which asserts that every nn-dimensional Busemann GG-space is a topological nn-manifold. We also prove that every Busemann GG-space which is uniformly locally GG-homogeneous on an orbal subset must be finite-dimensional.
