Electronic Transactions on Numerical Analysis《数值分析电子会报》（不定期）. The Electronic Transactions on Numerical Analysis (ETNA) is an electronic journal for the publication of significant new developments in numerical analysis and scientific computing. Papers of the highest quality that deal with the development and analysis of numerical methods, including rigorous studies of the convergence of algorithms, their accuracy, stability, and complexity. Numerical methods for the solution of continuous models as well as papers in numerical linear algebra are appropriate for ETNA, as are papers of similar quality that discuss implementation and performance of such algorithms.

Electronic Research Archive《电子研究档案》（月刊）. 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.

Electronic Journal of Statistics《美国统计学电子期刊》（半年刊）. The Electronic Journal of Statistics (EJS) publishes research articles and short notes on theoretical, computational and applied statistics. The journal is open access. Articles are refereed and are held to the same standard as articles in other IMS journals. Articles become publicly available shortly after they are accepted.

Electronic Journal of Qualitative Theory of Differential Equations《微分方程定性理论电子期刊》（一年1卷）. The Electronic Journal of Qualitative Theory of Differential Equations (EJQTDE) is a completely open access journal dedicated to bringing you high quality papers on the qualitative theory of differential equations.

Electronic Journal of Probability《概率学电子期刊》（年刊）. The Electronic Journal of Probability (EJP) publishes full-length research articles in probability theory. Short papers, those less than 12 pages, should be submitted first to its sister journal, the Electronic Communications in Probability (ECP). EJP and ECP share the same editorial board, but with different Editors in Chief.

The Electronic Journal of Linear Algebra《线性代数电子期刊》（年刊）. The Electronic Journal of Linear Algebra (ELA), a publication of the International Linear Algebra Society (ILAS), is a refereed all-electronic journal that welcomes mathematical articles of high standards that contribute new information and new insights to matrix analysis and the various aspects of linear algebra and its applications. ELA is a JCR ranked journal, and indexed by MathSciNet, ZentralBlatt, and Scopus. ELA is completely free for authors/readers; and ELA is built on the selfless contributions of its authors, referees and editors.

Electronic Journal of Differential Equations《微分方程电子杂志》（一年1卷）. Since its foundation in 1993, this e-journal has been dedicated to the rapid dissemination of high quality research in mathematics.
