On weakly conformally symmetric pseudo-Riemannian manifolds

, 2017
In this paper, we study the properties of weakly conformally symmetric pseudo-Riemannian manifolds focusing particularly on the 4-dimensional Lorentzian case.

Weakly compact embedding of non-commutative symmetric spaces

e-Journal of Analysis and Applied Mathematics
In this paper, we prove that the embeddings of certain well-known symmetric spaces are weakly compact. Our main results concern noncommutative Lorentz and Marcinkiewicz spaces on finite von Neumann algebras.

On convergence completeness in symmetric spaces

, 2008
The notion of a convergence complete symmetric space is introduced in [6]. In this paper we shall show that every symmetric space admits a weakly S-convergence complete symmetric space.

Block sensitivity of weakly symmetric functions Theoretical

, 2008
. Block sensitivity, which was introduced by Nisan [5], is one of the most useful measures of boolean functions. In this paper we investigate the block sensitivity of weakly symmetric functions (functions invariant under some transitive group action). We

Some special Z-symmetric manifolds with applications to space-times and Ricci solitons

<p>This work aims to investigate various properties of some special Z-symmetric manifolds and their applications on space-times. Having an important place of the study, classifications of second-order symmetric tensor fields on space-times and ...
