Journal of Computational and Applied Mathematics

Journal of Computational and Applied Mathematics (commonly abbreviated as J. Comput. Appl. Math.) is a computational mathematics journal published by Elsevier. Founded in 1975, it carries a 2025 impact factor of 2.4.Journal of Computational and Applied Mathematics（常用缩写 J. Comput. Appl. Math.）是 Elsevier 出版的计算数学期刊，1975 年创刊，2025 年影响因子为 2.4。^[1]

Scope

• Scope: the journal publishes original papers of high scientific value in all areas of computational and applied mathematics, with its main interest in papers that describe and analyse new computational techniques for solving scientific or engineering problems.学科定位： 期刊发表计算与应用数学各领域的高科学价值原创论文，主要兴趣在于描述并分析求解科学或工程问题的新计算技术。
• Standards: improved analysis of existing methods and algorithms matters too, and computational efficiency such as convergence, stability and accuracy should be proved and illustrated by nontrivial numerical examples.办刊要求： 对既有方法与算法的改进分析同样受到重视，计算效率——如收敛性、稳定性与精度——须以非平凡数值算例证明与展示。
• Explicit exclusions: papers describing only variants of existing methods without substantive advance are not considered.明确不收： 期刊不收仅对既有方法作变体而无实质推进的论文。
• Publishing model: the journal is subscription-based with an open access option available.出版模式： 期刊为订阅型刊物，支持开放获取发表选项。
• Indexing and metrics: indexed in the Science Citation Index Expanded, the journal holds a first-quartile position in applied mathematics, with a 2025 impact factor of 2.4.收录与指标： 被科学引文索引扩展版收录，在应用数学类别中列第一区，2025 年影响因子为 2.4。^[2]

History

• Founded in 1975: the journal was launched by Elsevier in 1975, riding the rapid growth of computational mathematics within numerical analysis.1975年创刊： 期刊于 1975 年由 Elsevier 创刊，承载计算数学在数值分析浪潮中的快速增长。
• Editorial system: the journal organises refereeing through principal editors, and special issue proposals are no longer taken directly by email but via an official guideline process.出版体制： 期刊采用主编制组织审稿，专号提案不再经电邮直接受理，改走官方指南流程。^[3]
• Memorial tradition: the journal carried an in memoriam note for its late editor Marc Goovaerts.纪念传统： 期刊曾为已故编辑 Marc Goovaerts 发布纪念讣告，体现编委会的纪念传统。
• Recent metrics: the impact factor stood at 2.037 in 2019, 2.872 in 2021 and 2.4 in 2025.近年指标： 影响因子 2019 年为 2.037，2021 年为 2.872，2025 年为 2.4。
• Frequency: the journal appears semimonthly with twenty-four issues a year.刊期： 期刊为半月刊，每年出版 24 期。

Editors

• Editorial team: the journal is run by several editors, with long-standing names including Yalchin Efendiev of Texas A&M University, Taketomo Mitsui of Nagoya University, Michael Kwok-Po Ng of Hong Kong Baptist University and Fatih Tank of Atilim University in Türkiye.主编团队： 编辑团队由多位主编组成，长期列名者包括德克萨斯农工大学的 Yalchin Efendiev、名古屋大学的 Taketomo Mitsui、香港浸会大学的 Michael Kwok-Po Ng 与土耳其 Atilim 大学的 Fatih Tank 等。
• New appointments: in April 2026 Zhong-Zhi Bai of the Chinese Academy of Sciences and Eric Chung of the Chinese University of Hong Kong joined the editorial team as principal editors.新任主编： 2026 年 4 月，中国科学院的 Zhong-Zhi Bai 与香港中文大学的 Eric Chung 以主编身份加入编辑团队。^[4]
• Editorial board: the board spans numerical solution of ordinary differential equations, numerical linear algebra, multiscale simulation and uncertainty quantification.编委构成： 编委会覆盖常微分方程数值解、数值线性代数、多尺度模拟与不确定性量化等方向。
• Submission and peer review: manuscripts are lodged through Editorial Manager and undergo peer review.投稿与评审： 稿件经 Editorial Manager 在线系统递交，接受同行评审。
• Editorial policy: the journal weighs numerical evidence alongside theoretical proof, turning away method variants without substantive gain.编辑方针： 期刊强调数值例证与理论证明并重，反对缺乏实质增量的方法变体。
