Curvature properties of pseudosymmetry type of some 2-quasi-Einstein manifolds

Autor: Deszcz, Ryszard, Głogowska, Małgorzata, Jełowicki, Jan, Petrović-Torgašev, Miroslava, Zafindratafa, Georges

We determine pseudosymmetry type curvature conditions of some 2-quasi-Einstein manifolds (M,g), dim M > 3, with the Riemann-Christoffel curvature tensor R expresed by a linear combination of Kulkarni-Nomizu products formed by the metric tensor g, the

On Wintgen ideal submanifolds satisfying some pseudo-symmetry type curvature conditions

Autor: Deszcz, Ryszard, Głogowska, Małgorzata, Petrović-Torgašev, Miroslava, Zafindratafa, Georges

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 and C be the metric tensor, the Riemann-Christoffel curvature tensor,

On semi-Riemannian manifolds satisfying some generalized Einstein metric conditions

Autor: Deszcz, Ryszard, Głogowska, Małgorzata, Hotloś, Marian, Petrović-Torgašev, Miroslava, Zafindratafa, Georges

The difference tensor R.C-C.R of a semi-Riemannian manifold (M,g), dim M > 3, formed by its Riemannian-Christoffel curvature tensor R and the Weyl conformal curvature tensor C, under some assumptions, can be expressed as a linear combination of (0,6)

A note on some generalized curvature tensor

Autor: Deszcz, Ryszard, Głogowska, Małgorzata, Hotloś, Marian, Petrović-Torgašev, Miroslava, Zafindratafa, Georges

For any semi-Riemannian manifold (M,g) we define some generalized curvature tensor as a linear combination of Kulkarni-Nomizu products formed by the metric tensor, the Ricci tensor and its square of given manifold. That tensor is closely related to q

Hypersurfaces in spaces of constant curvature satisfying a particular Roter type equation

Autor: Deszcz, Ryszard, Głogowska, Małgorzata, Hotloś, Marian, Sawicz, Katarzyna

We investigate hypersurfaces M isometrically immersed in an (n+1)-dimensional semi-Riemannian space of constant curvature, n > 3, such that the operator A^3, where A is the shape operator of M, is a linear combination of the operators A^2 and A and t
