Abstract

The author reviews his results on locally compact homogeneous spaces with inner metric, in particular, homogeneous manifolds with inner metric. The latter are isometric to homogeneous (sub-)Finslerian manifolds; under some additional conditions they are isometric to homogeneous (sub)-Riemannian manifolds. The class Ω\Omega of all locally compact homogeneous spaces with inner metric is supplied with some metric dBGHd_{BGH} such that 1) (Ω,dBGH)(\Omega,d_{BGH}) is a complete metric space; 2) a sequences in (Ω,dBGH)(\Omega,d_{BGH}) is converging if and only if it is converging in Gromov-Hausdorff sense; 3) the subclasses M\mathfrak{M} of homogeneous manifolds with inner metric and LG\mathfrak{LG} of connected Lie groups with left-invariant Finslerian metric are everywhere dense in (Ω,dBGH).(\Omega,d_{BGH}). It is given a metric characterization of Carnot groups with left-invariant sub-Finslerian metric. At the end are described homogeneous manifolds such that any invariant inner metric on any of them is Finslerian.
