Curvature properties of pseudosymmetry type of some 2-quasi-Einstein manifolds
Ryszard Deszcz, Małgorzata Głogowska, Jan Jełowicki +2
Let (M,g) be a 2-quasi-Einstein non-conformally flat semi-Riemannian manifold of dimension > 3. We prove that if its Riemann-Christoffel curvature tensor R is a linear combination…

On Wintgen ideal submanifolds satisfying some pseudo-symmetry type curvature conditions
Ryszard Deszcz, Małgorzata Głogowska, Miroslava Petrović-Torgašev +1
Let M be a Wintgen ideal submanifold of dimension n in a real space form R^{n+m}(k) of dimension (n+m) and of constant curvature k, n > 3, m = 1 or m > 1. Let g, R, Ricc, g /\ Ricc…
