Special Issue Information
Dear Colleagues,
The late-time cosmic speed-up phenomenon, as witnessed in recent observations, has triggered the development of new ideas and concepts. Einstein’s general relativity (GR) theory is able to explain such a phenomenon through the incorporation of additional dynamical degrees of freedom, such as quintessence, tachyons, phantom fields, etc., usually dubbed as dark energy candidates. However, geometrically modified theories of gravity can handle this issue without the need for any dark energy candidates. On the other hand, theoretical shortcomings and tensions between different cosmological observations have raised questions about GR, at least at the large energy scale. Additionally, questions about the symmetrical expansion of the universe have arisen. In this context, symmetry plays an important role in addressing many issues arising in the fields of cosmology and astrophysics. Usually, for a dynamical system, different symmetries, such Noether symmetry and the non-local conservation laws, help to simplify the system of equations, allowing physical systems to be studied in an analytic manner.
This Special Issue aims to present the role played by symmetries and conservation laws in addressing issues in gravitation and cosmology concerning recent research challenges.

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.
