The Unit Re-Balancing Problem

Autor: Robin Dee, Armin Fügenschuh, George Kaimakamis

We describe the problem of re-balancing a number of units distributed over a geographic area. Each unit consists of a number of components. A value between 0 and 1 describes the current rating of each component. By a piecewise linear function, this v

On a New type of Tensor on Real Hypersurfaces in Non-Flat Complex Space Forms

Autor: George Kaimakamis, Konstantina Panagiotidou

Publikováno v: Symmetry, Vol 11, Iss 4, p 559 (2019)

In this paper the notion of ∗ -Weyl curvature tensor on real hypersurfaces in non-flat complex space forms is introduced. It is related to the ∗ -Ricci tensor of a real hypersurface. The aim of this paper is to provide two classification theore

Derivatives of the Operator $$\phi A-A\phi $$ϕA-Aϕ on a Real Hypersurface in Non-flat Complex Space Forms

On a real hypersurface M in a non-flat complex space form, two types of connections can be defined: the Levi-Civita connection, which is torsion free and, for any nonnull constant k, the kth generalized Tanaka-Webster connection, which is an affine c
