Killing tensors of Weyl's class
Dionysios Kokkinos
This work represents an initial step towards a systematic framework for identifying hidden symmetries in algebraically general (Petrov type I) spacetimes. Motivated by this, we foc…

A Directive for obtaining Algebraically General Solutions of Einstein Equations Based on the Canonical Killing Tensor Forms
Dionysios Kokkinos, Taxiarchis Papakostas
This work follows earlier investigations in which the existence of canonical Killing tensor forms and the application of general null tetrad transformations led to a variety of sol…

The Study of the Canonical forms of Killing tensor in vacuum with Λ
Dionysios Kokkinos, Taxiarchis Papakostas
This paper is the initial part of a comprehensive study of spacetimes that admit the canonical forms of Killing tensor in General Relativity. The general scope of the study is to d…
