Sažetak

We present two classical conjectures concerning the characterization
of manifolds: the Bing Borsuk conjecture asserts that every
n-dimensional homogeneous ANR is a topological n-manifold,
whereas the Busemann conjecture asserts that every n-dimensional
G-space is a topological n-manifold. The key object in both
cases are so-called i.e. ENR homology manifolds. We look at the history from the early beginnings to the present day. We also list several open problems and related conjectures.
