Modified Gravity and Related Symmetries

Dear Colleagues,

We are pleased to announce a Special Issue of Symmetry, titled "Modified Gravity and Related Symmetries", and invite you to contribute your research to this exciting collection.

Despite its tremendous success, Einstein's general relativity is not free of shortcomings. The study of modified gravity theories has recently become a cornerstone of modern theoretical physics, offering profound insights into the nature of spacetime, cosmology, and the fundamental symmetries which underpin our understanding of the universe. This Special Issue aims to explore the interplay between modified gravity theories and the symmetries that govern them, including but not limited to Lorentz invariance, diffeomorphism invariance, de Sitter invariance, Anti de Sitter invariance, scale invariance, etc.

We welcome contributions that address both theoretical developments and observational implications of modified gravity, as well as their connections to symmetry principles. We encourage submissions of original research articles, reviews, and perspectives that advance our understanding of these topics.

Topics of Interest:

• Modified theories of gravity (e.g., non-local gravity, f(R), f(T), scalar–tensor theories, Horndeski gravity, etc.);
• Symmetries in gravitational theories and their breaking;
• Noether symmetries and conservation laws in modified gravity;
• Cosmological implications of modified gravity and symmetry principles;
• Black hole solutions and their symmetries in alternative gravity theories;
• Quantum gravity, string theory, and symmetry considerations;
• Observational tests of modified gravity and their relation to symmetries;
• Mathematical foundations of symmetries in gravitational physics.

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.
