acta.hu is the official archive website for Acta Scientiarum Mathematicarum, a mathematics academic journal operated by the Bolyai Institute at the University of Szeged in Hungary. Founded by the renowned mathematicians Alfréd Haar and Frigyes Riesz, it is a long-established specialist journal in fields such as functional analysis and holds formal ISSN numbers (print: 0001-6969, online: 2064-8316).
The site is essentially a paper archive, holding the contents of journal volumes published before 2022. Users can browse by volume via the left-hand menu. New issues from 2022 onward, author submissions, and the latest information have all moved to the Springer publishing platform; this site no longer handles submissions and is positioned more toward preserving historical material.
It adopts a hybrid access model: papers published more than 10 years ago can be downloaded in full for free; for newer papers (within 10 years) that are archived here, you can only view the first page (abstract level) without a subscription. Overall it is very generous with older papers, in line with the open-access conventions of most academic journals.
The strengths lie in its strong authority and deep historical legacy—maintained by a reputable university institute, it has high credibility, and a large body of classic mathematical literature is freely available. The downsides are also clear: the site has a dated design and lacks modern features like full-text search and citation export; the latest content requires redirecting to Springer, creating a fragmented user experience; and some papers are behind a subscription paywall.
It is mainly aimed at mathematics researchers, university faculty and students, and scholars who need to consult historical literature in fields such as functional analysis and operator theory. Users seeking the latest research findings should go directly to the Springer platform.
The site consists of static academic pages, with servers located in Hungary. It is generally directly accessible from within China, with no obvious blocking. Downloading newer papers may require a subscription, which depends on your institution's access privileges.
