Acta Mathematica

Acta Mathematica, with the abbreviation Acta Math-Djursholm and ISSN 0001-5962, stands as one of the most prestigious and selective journals in the field of pure mathematics. Published by the Institut Mittag-Leffler, a leading research institute under the Royal Swedish Academy of Sciences, the journal maintains a rigorous tradition of publishing only the highest quality original research. Its scope encompasses all major branches of pure mathematics, including algebra, analysis, geometry, topology, number theory, and mathematical logic, with a particular emphasis on groundbreaking contributions that significantly advance the discipline. The journal exclusively publishes full-length research articles; it does not feature review articles, short communications, or technical notes, ensuring that each paper represents a substantial and complete work of scholarship. The target audience consists primarily of professional mathematicians, academic researchers, and advanced doctoral students who seek to stay at the forefront of theoretical developments. A notable feature of Acta Mathematica is its commitment to open access; all articles are freely available online immediately upon publication, supported by the journal’s nonprofit publisher, facilitating global dissemination of knowledge without subscription barriers. With an Impact Factor of 7.300 as of 2026, the journal occupies the highest tier (Q1) in the Journal Citation Reports for mathematics, reflecting its exceptional citation impact and influence. This combination of a deeply selective editorial process, a focus on seminal research, and open access makes Acta Mathematica a cornerstone publication, widely regarded as one of the top two or three mathematics journals in the world.
