Communications in Mathematics is a diamond open-access free journal, with no author processing fees of any sort, and in which all articles can be freely downloaded that has been publishing research and survey papers in mathematics since 1993. The journal was originally established under the name Acta Mathematica et Informatica Universitatis Ostraviensis (ISSN 1211-4774), before undergoing a name change in 2003 to Acta Mathematica Universitatis Ostraviensis (ISSN 1214-8148). In 2009, the journal adopted its current name and has since been reviewed in the mathematical community, with reviews in Mathematical Reviews, ZbMATH, and indexing in Scopus. We invite you to explore the wealth of knowledge and innovative research contained within our pages.
