Noether’s Symmetry Approach in Gravity and Cosmology

Dear Colleagues,

The Noether’s theorem is one of the most beautiful theorems in mathematics that allows us to find symmetries for a certain model, to then to use them to reduce its dynamical system and find exact solutions. This theorem has been widely used in gravity and cosmology to find exact solutions.

An enormous literature exists about modified theories of gravity, but these theories have (in general) complicated partial differential equations, and therefore, it is not so easy to find exact solutions for those models. To go beyond general relativity (GR) or the standard model of cosmology, it is important to investigue and find new exact solutions, to then compare them with the standard solutions known in GR. This might help to analyse the differences between modified theories and GR. The main aim of this Special Edition is to invite researchers from the subjects of gravity and cosmology to submit their work, in which one can use the Noether’s symmetry approach to find exact solutions.

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.
