On Sasakian quasi-Killing spinors in three-dimensions
Satsuki Matsuno, Fumihiro Ueno
A Sasakian quasi-Killing spinor (SqK-spinor), which is a generalization of a Killing spinor on Sasakian manifolds, was defined in \cite{Kim Friedrich 2000}.The purpose of this pape…

The exact solutions to an Einstein-Dirac-Maxwell system with Sasakian quasi-Killing spinors on 4D spacetimes
Satsuki Matsuno, Fumihiro Ueno
Exact solutions to an Einstein-Maxwell(E-D-M) system with an electric current are simple models of global cosmic magnetic phenomena in the universe. In this paper, we consider an E…
