On semisymmetric para-Kähler manifolds
The main results in the paper are: Theorem 3.3. Every Ricci-generalized pseudosymmetric para-Kähler manifold \((M,g,I)\), \(\dim M\geq 4\), is Ricci-semisymmetric. Theorem 4.1. Every para-Kähler hypersurface of a semi-Euclidean space \(E^{2m+1}_u\), \(m\geq 2\), of index \(u\), is semisymmetric.
