Helical symmetry, spinors and periodic solutions in general relativity: Spinors and conformal techniques in general relativity w,Used
Delivery time: 8-12 business days (International)
This book is an extended version of the thesis defended by the author in 2011. It contains an introduction to the formalism of twocomponent spinors in general relativity and conformal techniques related to asymptotically flat spacetimes. These techniques are then applied to the problem of the nonexistence of asympotically flat periodic solutions of Einstein's equations. It is shown that such solutions in fact do not exist which, roughly speaking, means that gravitational field of isolated gravitating systems cannot be periodic. Proof of this statement arose with the collaboration of the author, his former supervisor prof. Jir Bick from Charles University in Prague and prof. Paul Tod from University of Oxford. In the book, the notion of helical symmetry is introduced as a special kind of periodicity and new helically symmetric solutions in electrodynamics and linearized gravity are presented. In the second part, the formalism of 2spinors is introduced together with the NewmanPenrose formalism. Finally, in the third part, we present the proof of the nonexistence of periodic solutions of Einstein's equations which was published in Classical and Quantum Gravity journal in 2010.
