Electronic Research Archive (ERA), formerly known as Electronic Research Announcements in Mathematical Sciences, publishes original and expository full-length research articles of significant advances in all branches of mathematics, applied mathematics and related fields. All articles should be written to communicate their contents to a broad scientific audience and must meet high standards for scientific content and clarity.
Ever since ERA was created by the American Mathematical Society in 1995, the journal has been serving well the community, with its full contents free of charge for both readers/libraries and authors. This has been an extraordinary contribution to the community by AMS and AIMS for over 20 years. To ensure the sustainability of the journal, ERA has been Open Access since 2022, and publishes monthly.
