Special Issue Information

Dear Colleagues,

General relativity is a very successful theory that shows great agreement with observations. However, the theory faces some theoretical and observational challenges, such as the issues surrounding dark energy or dark matter as well as cosmological tensions in recent large-scale structure measurements. In order to try to tackle these issues, several types of modified theories of gravity have been proposed. One interesting route is to modify the geometrical nature of gravity. This is done in the so-called “teleparallel theories of gravity”, where the manifold is assumed to be flat (zero curvature) but could contain torsion and/or non-metricity. It turns out that one can write down theories having the same field equations (and predictions) to general relativity using two alternative routes: from torsion (torsional teleparallel) or from non-metricity (symmetric teleparallel). Following this, one could extend these theories to obtain modified theories different from the standard GR-based theories. 

This Special issue is devoted to all aspects of teleparallel theories of gravity, containing torsion and/or non-metricity. The main aim would be to focus on their theoretical foundations and, also, on possible observational constraints that one can set from cosmology and astrophysics.

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 papers will be 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. Universe is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. 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.
