چکیده

We give an algebraic characterization of the case when conformal Weyl and conformal Lyra connections have the same curvature tensor. It is determined a (1,3)-tensor field invariant to certain transformation of semi-symmetric connections, compatible with Weyl structures on conformal manifolds. It is studied the case when this tensor is vanishing. M.S.C. 2000: 53B05, 53B20, 53B21.

Conformal mappings preserving the Einstein tensor of Weyl manifolds

In this paper, we obtain a necessary and sufficient condition for a conformal mapping between two Weyl manifolds to preserve Einstein tensor. Then we prove that some basic curvature tensors of $W_n$ are preserved by such a conformal mapping if and only if the covector field of the mapping is locally a gradient. Also, we obtained the relation between the scalar curvatures of the Weyl manifolds r...

The conformal analog of Calabi-Yau manifolds

This survey intends to introduce the reader to holonomy theory of Cartan connections. Special attention is given to the normal conformal Cartan connection, uniquely defined for a class of conformally equivalent metrics, and to its holonomy group the ’conformal holonomy group’. We explain the relation between conformal holonomy group and existence of Einstein metrics in the conformal class as we...

A Calculus for Differential Invariants of Parabolic Geometries

The Wünsch’s calculus for conformal Riemannian invariants is reformulated and essentially generalized to all parabolic geometries. Our approach is based on the canonical Cartan connections and the Weyl connections underlying all such geometries. The differential invariants for various geometric structures are the core ingredients for numerous applications both in geometry and geometric analysis...

Curvature relations in almost product manifolds

New relations involving curvature components for the various connections appearing in the theory of almost product manifolds are given and the conformal behaviour of these connections are studied. New identities for the irreducible parts of the deformation tensor are derived. Some direct physical applications in Kaluza–Klein and gauge theory are discussed. [email protected] [email protected]
