Projective structures in Sinyukov manifolds. (English) Zbl 0795.53018
Szenthe, J. (ed.) et al., Differential geometry and its applications. Proceedings of a colloquium, held in Eger, Hungary, August 20-25, 1989, organized by the János Bolyai Mathematical Society. Amsterdam: North- Holland Publishing Company. Colloq. Math. Soc. János Bolyai. 56, 263-271 (1992).
The author studies geodesic mappings on Sinyukov manifolds, i.e. in Sinyukov’s terms $$L_ n$$-spaces satisfying the following conditions: $$R_{ij,k} = a_ kg_{ij} + b_ i g_{jk} + b_ i g_{ik}$$ where $$R_{ij}$$ and $$g_{ij}$$ denote Ricci and metric tensors, $$a_ k,b_ k$$ are covectors. If an Einstein space admits geodesic mappings then it corresponds to a certain Sinyukov manifold.
