Pacific Journal of Mathematics《太平洋数学杂志》（月刊）. Founded in 1951, PJM has published mathematics research for more than 60 years. PJM is run by mathematicians from the Pacific Rim. PJM aims to publish high-quality articles in all branches of mathematics, at low cost to libraries and individuals. The Pacific Journal of Mathematics is incorporated as a 501(c)(3) California nonprofit.

Osaka Journal of Mathematics《大阪数学期刊》（季刊）. Osaka Journal of Mathematics is published quarterly by the joint editorship of the Department of Mathematics, Graduate School of Science, Osaka University, and the Department of Mathematics, Graduate School of Science, Osaka Metropolitan University and the Department of Pure and Applied Mathematics, Graduate School of Information Science and Technology, Osaka University with the cooperation of the Department of Mathematical Sciences, Faculty of Engineering Science, Osaka University. The Journal is devoted entirely to the publication of original works in pure and applied mathematics.

Order-A Journal on the Theory of Ordered Sets and its Applications《序：有序集理论及其应用杂志》（一年3期）. Order presents the most original and innovative research on ordered structures and the use of order-theoretic methods in graph theory and combinatorics, lattice theory and algebra, set theory and relational structures, and the theory of computing. In each of these categories, we seek submissions that make significant use of orderings to study mathematical structures and processes. The interplay of order and combinatorics is of particular interest, as are the application of order-theoretic tools to algorithms in discrete mathematics and computing. Articles on both finite and infinite order theory are welcome.

Optimization Methods & Software《最优化方法与软件》（双月刊）. Optimization Methods and Software publishes refereed papers on the latest developments in the theory and realization of optimization methods, with particular emphasis on the interface between software development and algorithm design.

Optimization Letters《优化快报》（一年9期）. Optimization Letters is an international journal covering all aspects of optimization, including theory, algorithms, computational studies, and applications, and providing an outlet for rapid publication of short communications in the field. Originality, significance, quality and clarity are the essential criteria for choosing the material to be published.

Optimization and Engineering《优化与工程》（季刊）. Optimization and Engineering is a multidisciplinary journal; its primary goal is to promote the application of optimization methods in the general area of engineering sciences. We expect submissions to OPTE not only to make a significant optimization contribution but also to impact a specific engineering application.

Optimization《优化》（月刊）. Optimization publishes refereed, theoretical and applied papers on the latest developments in fields such as linear, nonlinear, stochastic, parametric, discrete and dynamic programming, control theory and game theory.

Optimal Control Applications and Methods《最优控制应用与方法》（双月刊）. Optimal Control Applications and Methods will provide a forum for papers on the full range of optimal control and related control design methods. The aim is to encourage new developments in optimal control theory and design methodologies that may lead to advances in real control applications. Papers are encouraged on the development of computational algorithms for solving optimal control and optimization problems.

Operators and Matrices《算子与矩阵》（季刊）. Operators and Matrices (OaM) aims towards developing a high standard international journal which will publish top quality research and expository papers in matrix and operator theory and their applications. The journal will publish mainly pure mathematics, but occasionally papers of a more applied nature could be accepted. OaM will also publish relevant book reviews.

Open Systems & Information Dynamics《开放系统与信息动力学》（季刊）. The aim of the Journal is to promote interdisciplinary research in mathematics, physics, engineering and life sciences centered around the issues of broadly understood information processing, storage and transmission, in both quantum and classical settings. Our special interest lies in the information-theoretic approach to phenomena dealing with dynamics and thermodynamics, control, communication, filtering, memory and cooperative behaviour, etc., in open complex systems.
