Special Issue Information
Dear Colleagues,
General relativity, gravitation, and cosmology are fields where the role of symmetry is quite relevant. Such a property can be used to simplify the treatment of non-trivial problems and help with the obtention of exact solutions. To be more precise, spacetime symmetries were originally used in the study of exact solutions of Einstein’s field equations in the context of general relativity, and subsequently, in alternative theories of gravity. It is well known that there are different symmetries (Killing symmetry, Conformal symmetry, etc.), and only after taking advantage of them can we achieve progress. There are several remarkable examples in which the implementation of the idea of symmetry plays a prominent role. For instance, in black hole physics, the well-known Schwarzschild solution can be easily computed after considering spherical symmetry. Similarly, the famous BTZ black hole takes advantage of circular symmetry to make progress in three dimensions. There are also examples where symmetry is the cornerstone in the cosmological context, e.g., dictating the type of universe to be considered. Thus, in the Special Issue, we would like to focus on the impact of different types of symmetries on black holes and cosmological models.

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 100 words) can be sent to the Editorial Office for announcement on this website.
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.
