Dear Authors and Visitors, Due to the high volume of daily manuscript submissions, the editorial workflow of BAREKENG: Journal of Mathematics and Its Applications is currently very intensive, resulting in a substantial workload for our editors. In addition, our publisher Universitas Pattimura is implementing improvements to the journal’s governance and editorial management. Therefore, the journal is temporarily suspending the acceptance of new submissions. This measure will allow the editorial team to focus on completing the processing and publication targets for manuscripts that are already in progress within the BAREKENG OJS system. Information regarding the reopening of submissions will be announced in due course on the official BAREKENG journal website.
Thank you for your understanding and continued support.
Sincerely,
Editorial Team of BAREKENG: J. Math. & App.
