Announcements

To develop different research areas and continue to attract high-quality papers, Axioms (ISSN 2075-1680) is recruiting Section Editors-in-Chief (more details can be found at https://www.mdpi.com/journal/axioms/sections).

At present, the following Sections have not yet found suitable scholars to lead them:

• “Algebra and Number Theory”;
• “Geometry and Topology”;
• “Logic”.

We are now recruiting Section Editors-in-Chief (SEiCs) for these Sections. If you are an active researcher in one of the aforementioned fields and are passionate about publishing cutting-edge research, please do not hesitate to contact us at axioms@mdpi.com. You can find more information on our homepage: https://www.mdpi.com/journal/axioms.

The Section Editor-in-Chief has the following responsibilities:

• Making decisions on whether a manuscript can be accepted based on the reports that we collect;
• Reviewing a small number of papers per year and managing the Section together with other journal editors;
• Promoting Axioms and increasing its visibility at related academic conferences.

Axioms is an international, peer-reviewed, and open access journal of mathematics, mathematical logic, and mathematical physics, published monthly online by MDPI. The European Society for Fuzzy Logic and Technology (EUSFLAT), the International Fuzzy Systems Association (IFSA), and the Union of Slovak Mathematicians and Physicists (JSMF) are affiliated with Axioms, and their members receive discounts on the article processing charge.

We believe that by combining our rigorous editorial policies with your expertise, we can build a high-quality journal. We thank you in advance for your interest and look forward to collaborating with you in the future.
