Advanced Nonlinear Studies publishes work on nonlinear problems, with differential equations and dynamical systems at the centre and applications to engineering and the sciences at the edge.《Advanced Nonlinear Studies》发表非线性问题的研究，中心是微分方程与动力系统，边缘是这些方法在工程与科学里的应用。
The journal's own statement is demanding. Papers must contain original, timely and significant results, and a manuscript that only pushes a known estimate a little further is not the target.刊物自己的说法很硬。论文必须包含原创、及时且有分量的结果，只把已知估计往前推一点的手稿不是它要的。
Order of appearance is set by arrival. Articles are printed in the order their final copies were received, not by subject and not by the standing of the author.登载次序按到稿时间定。论文依收到的定稿先后排列，不按题目分类，也不看作者资历。
Nonlinear elliptic theory is the historical core. Choquard equations, Schrödinger–Poisson systems, Trudinger–Moser inequalities and critical exponent problems recur across the volumes.非线性椭圆理论是历史内核。肖夸尔方程与薛定谔–泊松系统各有一批，特鲁丁格–莫泽不等式与临界指数问题也不断出现。
Degenerate and anisotropic operators have grown in share, with double phase problems, singular Finsler double phase problems and anisotropic p-Laplacian evolution all appearing in recent volumes.退化与各向异性算子的比重在上升。双相问题与奇异芬斯勒双相问题都出现过，各向异性 p 拉普拉斯演化也在近几卷里。
Calculus of variations supplies the method. Minimax theorems, mountain-pass arguments and linking theorems appear in the titles as often as the equations they solve.变分法是方法来源。极小极大定理与山路引理在标题里出现的频率，不亚于它们所解的方程。
Spectral and geometric problems sit alongside, with eigenvalue asymptotics for Witten Laplacians, Hardy and Adams inequalities on hyperbolic space and Pogorelov-type estimates for the sum Hessian equation.谱论与几何问题并排坐着，维滕拉普拉斯算子的特征值渐近有人做，双曲空间上的哈代与亚当斯不等式有人做，和式海森方程的波戈列洛夫型估计也有人做。
Stochastic and infinite-dimensional analysis has entered. Nonlinear stationary Fokker–Planck–Kolmogorov equations, sticky-reflected diffusions and kinetic stochastic equations with distributional drifts all appear in 2026.随机与无穷维分析已经进来。非线性定常 Fokker–Planck–Kolmogorov 方程、粘性反射扩散、带分布漂移的动力学随机方程，2026 年都出现过。
Mathematical physics has a visible presence. Gauge-invariant Gaussian operations on finite Fermi systems, confinement in three-dimensional lattice gauge theory and Makeenko–Migdal equations are in the current queue.数学物理有明显的存在感。有限费米系统上的规范不变高斯操作、三维格点规范理论的禁闭、Makeenko–Migdal 方程，都排在眼下的队列里。
Dynamical systems theory keeps its place, with Poincaré–Birkhoff theorems for degenerate planar Hamiltonian systems, subharmonic solutions obtained through rotation numbers and bifurcations of Hamiltonian systems.动力系统理论保住自己的位置。退化平面哈密顿系统的庞加莱–伯克霍夫定理、用旋转数求次调和解、哈密顿系统的分支问题，都能找到。
The journal prints no book reviews and no conference reports. Research papers and front matter are the whole content type.刊物不发书评，也不发会议报道。研究论文加前置页就是全部内容类型。
Front matter is deposited with each issue. Volume 26, issue 2 carries one record of that kind beside twelve research papers.前置页随每期存入。第 26 卷第 2 期除十二篇研究论文外，还有一条前置页记录。
Length follows the argument. A paper that needs forty pages gets them, and the page design serves the formulas rather than the other way round.篇幅取决于论证需要。要四十页的论文就给四十页，版式跟着公式走。
History
The first volume appeared in 2001, published from San Antonio by UTHSCSA Press, the press of the University of Texas Health Science Center.第 1 卷出版于 2001 年，由设在圣安东尼奥的 UTHSCSA 出版社印行，那是得克萨斯大学健康科学中心的出版社。
Volume 1 carried two issues, and the numbering has run one volume a year since, reaching volume 26 in 2026.第 1 卷只有两期，此后一年一卷，到 2026 年是第 26 卷。
Ownership stayed in Texas. The journal is incorporated as Advanced Nonlinear Studies, Inc., with a mailing address in the city, and the managing editor is named on its own site.归属一直留在得克萨斯。刊物以 Advanced Nonlinear Studies 公司名义登记，通信地址就在这座城市，执行编辑的姓名也写在它自己的网站上。
De Gruyter took over production in Berlin, and the National Library of Medicine's imprint note records the transfer with the year 2016.De Gruyter 在柏林接手制作，美国国家医学图书馆的出版项注记以 2016 年为界记下这次转移。
Old identifiers were re-registered. The 2001 papers carry DOIs in the 10.1515 prefix, the publisher's own range, rather than an archive prefix.旧标识后来重新登记过。2001 年的论文带着 10.1515 前缀的 DOI，那是出版方自己的号段，不是另设的存档号。
Open access arrived in 2022. The directory record dates the switch to that year, and the gold share now stands at 100 percent.开放获取在 2022 年到位。目录记录把转换定在那一年，如今金色比例是百分之百。
That switch brought a charge. The article processing fee is 1,300 euros, which is what funds the journal now that subscriptions are gone.转换带来了收费。文章处理费是 1,300 欧元，订阅取消之后，刊物就靠这笔钱运转。
The archive holds 895 records over twenty-six volumes, about 34 a volume, and the 2025 count is 49 articles.存档共 895 条记录，分布在二十六卷里，平均每卷约 34 条，2025 年记了 49 篇。
Impact rose and then held. The factor was 1.446 in 2021, 1.682 in 2022, 2.1 in 2023, 2 in 2024 and 2.3 in 2025.影响因子升上去之后站住了。2021 年是 1.446，2022 年 1.682，2023 年 2.1，2024 年 2，2025 年 2.3。
The five-year factor is 2.4, above the current value, and the cited half-life is 7.3 years on a base of 1,331 citations.五年影响因子是 2.4，高于当年值，在 1,331 次引用的基数上，半衰期是 7.3 年。
Two categories carry it. The title ranks 28 of 492 in mathematics and 54 of 345 in applied mathematics, the same rank pair as Analysis and Applications.两个类目都收这份刊物。数学类 492 种里排第 28，应用数学类 345 种里排第 54，与《Analysis and Applications》是同一对排名。
Publication still trails acceptance. Sixteen items dated 2026 in the current queue carry 2023 DOI stems, which is a backlog printed rather than hidden.出版仍落后于录用。现行队列里十六篇 2026 年的条目带着 2023 年的 DOI 字串，这是一条印在纸上的积压记录。
Editors
Shair Ahmad is managing editor, and his name has been attached to the journal since its San Antonio years.执行编辑是 Shair Ahmad，从圣安东尼奥时期起，他的名字就一直挂在这份刊物上。
He was the founding editor at UTHSCSA and remains the contact point after the move to Berlin, which is unusual for a De Gruyter title.他在 UTHSCSA 时期是创刊编辑，转去柏林之后仍是联络人，这在 De Gruyter 的刊里并不常见。
Manuscripts go to an editor whose interests match the paper rather than to a central desk, and the instructions ask authors to pick that editor themselves.稿子寄给研究方向相符的某位编辑，不经过中心收稿台，投稿说明要求作者自己挑人。
The format instructions are precise. Papers are typeset in LaTeX at 5.0 by 7.5 inches, pages are numbered, and the abstract is capped at 400 words.格式说明写得很具体。论文用 LaTeX 排版，版心 5.0 乘 7.5 英寸，页要编号，摘要不超过 400 词。
Classification comes after the abstract. AMS subject codes and keywords are required there, and references are listed alphabetically rather than in citation order.分类号排在摘要之后。那里要写美国数学会的主题分类与关键词，参考文献按字母顺序列，不按引用顺序排。
Reprints travel by e-mail. Authors receive PDF files exactly as printed, with volume, number and pages visible, and may copy them as often as they like.抽印本用邮件发送。作者收到的 PDF 与印刷版完全相同，卷号与期号与页码都在上面，可以随意复制。
Published papers go out for review by Mathematical Reviews and by Zentralblatt für Mathematik, the two abstracting services the journal names.发表的论文会送交《数学评论》与《德国数学文摘》评介，这是刊物点名的两家文摘机构。
The site also lists the ISI products that carry it, naming the Science Citation Index Expanded, the CompuMath Citation Index and Research Alert.网站还列出收录它的 ISI 产品，点名科学引文索引扩展版、计算数学引文索引与 Research Alert。
A quarterly schedule governs the desk. Issues appear in February and May, then in August and November.季度日程管着编辑台。二月与五月各出一期，八月与十一月再各出一期。
The old site still describes the journal as a subscription title, an entry that has not been updated since the open access switch.旧网站仍把刊物说成订阅刊，这条说明自开放获取转换以来没有改过。
Front matter is deposited issue by issue, and the masthead is printed there rather than maintained as a web page.前置页按期刊出，名册印在那里，不靠网页维护。
Selection is by weight of result rather than by topic. A paper on lattice gauge theory and one on a Kirchhoff equation reach the same editors when the result is strong enough.取舍看结果的分量，不看题目归哪一科。格点规范理论的论文与基尔霍夫方程的论文，只要结果够硬，就送到同一批编辑手里。
