Symmetry in Relativity, Gravitation, and Cosmology

Dear Colleagues,

Symmetry plays a very important role in relativity, gravitation, and cosmology. Einstein’s field equations are a set of ten partial differential equations and are difficult to solve. Invariably, one has to invoke some symmetry to solve the equations. Most interesting solutions in relativity have some symmetry or the other, e.g., the Schwarzschild solution for a spherically symmetric body, the Kerr solution for an axisymmetric rotating body or the Friedmann–Lemaitre–Robertson–Walker solution for a homogeneous and isotropic universe in cosmology. While it is possible to find exact solutions with little or even no symmetry, such solutions are often of limited physical interest.

This Special Issue of Symmetry on relativity, gravitation, and cosmology will focus on all aspects relating to symmetry in these topics, ranging from symmetries and exact solutions, invariant properties of exact and numerical solutions, variational symmetries, conservation laws, and Noether symmetries to Lorentz and other symmetry groups. Starting from the symmetries of special relativity, there is a deep connection between symmetry and conservation laws, and the identification of the correct symmetry is absolutely essential.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Symmetry is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
