Most of JAT's former editors joined forces to launch a new online successor of JAT that we used to love and respect (but not anymore). It is published by Stanford University Press and it is called "Advances in Approximation Theory" (AAT) with Martin Buhmann, Feng Dai, András Kroó, and Sergey Tikhonov as the Editors-in-Chief, see, https://aat.journals.sup.org. I and our editors will be super appreciative and grateful if you helped us to make AAT viable, successful, and at least as respected as JAT used to be, by submitting your papers related to Approximation Theory to AAT. You can register as an Author, Reviewer, and Reader at https://aat.journals.sup.org/index.php/aat/user/register Please contact AAT at aat@nevai.us if you have any questions. We are looking forward to hearing from you and to processing your papers at AAT. In addition, please spread the word among your colleagues, coauthors, and friends. Please inform them and encourage them to submit papers to AAT. Gratefully, Paul Nevai ------------------------------------------------------- From: Tzanio Kolev kolev1@llnl.gov Date: September 02, 2026 Subject: MFEM Version 4.10 Version 4.10 of MFEM, a lightweight, general, scalable C++ library for finite element methods, is now available at: https://mfem.org.
