BGL2025: The 13th Bolyai–Gauss–Lobachevsky Conference on Non-Euclidean Geometry and Its Applications

Dear Colleagues,

This Special Issue is dedicated to the 13th Bolyai–Gauss–Lobachevsky Conference on Non-Euclidean Geometry and Its Applications (BGL2025), https://indico.cern.ch/event/1464707/.

Traditionally, the topics of the Bolyai–Gauss–Lobachevsky conference series cover three main areas:

• Mathematics: Non-Euclidean and Riemannian geometry;
• Physics: Non-Euclidian geometries and mathematical methods in modern physics, the cosmology of the early and late Universe, modified gravity theories, quantum mechanics, quantum information, quantum field theory, complex systems, chaos, and nonequilibrium phenomena;
• History of science: The historical development of Non-Euclidian and Riemannian geometry; the heritage of BGL; significant events in the evolution of science; scientific outreach.

The main goal of the conference, and of this Special Issue, is to create a lively environment in which recent advances in mathematics and physics can be shared between the participants, thus leading to a fruitful interaction and fertile dialogue between practitioners of various branches of mathematics and physics. The conference, as well as the Special Issue, is open to new and innovative ideas that could shape the future landscape of both physics and mathematics.

For this Special Issue, we invite submissions of talks in the following areas: cosmology, modified gravity theories, the Hubble tension, quantum gravity, quantum mechanics, quantum field theory, quantum computation, recent advances in high-energy physics and related fields, gravitational waves, and the physics of complex systems.

There is no maximal length, and the suggested minimum is approx. 4000 words. Submitted papers should contain enough novel contents (except for reviews, which are acceptable from senior contributors). Please note that the three paper types recommended for this special issue are Article, Review, and Communication (limited number). For more details, including various article types, please visit https://www.mdpi.com/about/article_types.

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. 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.
