CM, Communications in Mathematics, is a diamond open-access, electronic, international research journal that has been publishing research and survey articles in mathematics since 1993. In keeping with established tradition, the journal's primary topics include, but are not limited to, Algebra and Number Theory, Analysis, Geometry, and Topology. The journal was originally established as Acta Mathematica et Informatica Universitatis Ostraviensis (ISSN 1211-4774) before changing its name to Acta Mathematica Universitatis Ostraviensis (ISSN 1214-8148) in 2003. In 2009, the journal adopted its current name and has since been reviewed by the mathematical community, with reviews in Mathematical Reviews and ZbMATH, and indexed in Scopus. The journal does not charge author processing fees of any sort, and all published articles are available for free.

Editorial Board

The Editorial Board is composed of recognized experts in the area of Mathematics. It is responsible for defining the journal’s scientific scope, overseeing the selection of articles, and ensuring their quality. The Editorial Board guarantees that each submitted manuscript undergoes a rigorous peer-review process that is independent, transparent, and in accordance with the journal's academic standards. The Editorial Board is responsible for determining the rejection or request for revisions of manuscripts, monitoring the revised versions, and making the final decision on manuscript acceptance.
