This talk presents recent findings on the S-curvature of homogeneous Finsler spaces. We demonstrate that geodesic orbit Finsler spaces have vanishing S-curvature and construct examples of reversible non-Berwald spaces with this property. An explicit formula for the S-curvature of homogeneous Randers spaces is derived, followed by a complete classification of such spaces with positive flag curvature and vanishing S-curvature.
