Boundary Value Problems describes itself as a forum to promote, encourage and bring together the disciplines that use the theory, methods and applications of boundary value problems.《Boundary Value Problems》自称是一个论坛，用来推动并汇总那些用上边值问题理论、方法与应用的学科。
The core is a list of equation types. Ordinary, functional, difference, elliptic, parabolic and hyperbolic differential equations each get named in the aims statement.核心是一串方程类型。常微分、泛函、差分、椭圆、抛物与双曲这几类方程，范围说明里逐类点了名。
Singular boundary value problems, free boundary problems and ill-posed problems are all declared welcome, and so is work in abstract and concrete analysis that reaches the same objects by another route.奇性边值问题、自由边界问题与不适定问题都明说欢迎，从抽象分析或具体分析另一条路走到同一批对象的工作也欢迎。
Research articles are the staple and review articles are the only other type. There is no book review section and no conference report.研究论文是主粮，综述是唯一的另一种类型。没有书评栏目，也没有会议报道。
The annual volume is continuous. Articles appear under the volume as they are accepted, and the current volume carries the year as its number.年卷是连续出版的。论文录用后就挂在当年卷下，卷号直接用年份。
Online-first matters as much as the volume. In the hundred latest records, 37 carry no volume or issue at all, which means they are already citable before the annual volume reaches them.在线先发与卷号同等重要。最新一百条记录里有 37 条既无卷号也无期号，说明它们还没进年卷就已经可以被引用。
Fractional analysis is the heaviest single theme. One 2026 paper proves existence and uniqueness for a class of sequential Hilfer-type boundary value problems, and another handles q-fractional inclusions with p-Laplacian operators.分数阶分析是最重的一个主题。2026 年有篇论文为一类序列型 Hilfer 边值问题证明存在唯一性，另一篇处理带 p 拉普拉斯算子的 q 分数阶包含问题。
Machine learning has reached the boundary too. A 2026 article builds topology-aware neural operators for free boundary problems and attaches a certificate to the uncertainty.机器学习也走到了边界上。2026 年有篇文章为自由边界问题搭了带拓扑结构的神经算子，并给不确定性附上证书。
Fluid problems arrive in numbers. Hybrid nanofluid stagnation point flow appears beside a thermodynamic analysis of micropolar hybrid nanofluid, both with grid-independence checks rather than proofs.流体问题成批到来。混合纳米流体驻点流动与微极混合纳米流体的热力学分析挨着排，两篇做的都是网格无关性检验而不是证明。
Classical questions still hold their place. The Dirichlet problem for Poisson's equation in a right-isosceles triangle was worked out in 2026, and so was the identification of small defects in three-dimensional moulded objects.经典问题仍占位置。泊松方程在等腰直角三角形上的狄利克雷问题 2026 年还有人做，三维浇铸件里小缺陷的识别也在同期。
Dynamical readings of the same operators turn up beside the equilibrium ones. Bifurcation and chaos control in a conformable fractional logistic system sits in the same volume as a stability result for a thermoelastic Bresse system.同一批算子的动力系统读法与平衡态读法并排出现。可服从分数阶逻辑斯谛系统的分支与混沌控制，和热弹性 Bresse 系统的稳定性结果在同一卷里。
Not every paper matches the aims statement. An article on connectedness between ESG ratings and sectoral stock markets, and another on memory in a diffusive virus-immune model, both went through the same queue.并非每篇都对得上范围说明。一篇讲 ESG 评级与行业股市之间连通性的文章，另一篇讲扩散型病毒免疫模型里的记忆效应，走的是同一条队列。
Papers are moderate in length and authorship. The hundred latest carry an average of 3.4 authors, the widest team having eight.论文篇幅与署名规模都不大。最新一百条平均 3.4 位作者，最大的一支队伍八个人。
History
The first volume appeared in 2005 and carried three issues. Volume 1 of the deposit sets functional differential equations beside Seiberg–Witten equations and p-Laplacian problems, which is the classical core of the field.首卷 2005 年出版，出了三期。存录里的第 1 卷把泛函微分方程、Seiberg–Witten 方程与 p 拉普拉斯问题摆在一起，那是这一领域的经典内核。
The rhythm broke almost at once. 2006 has a single issue in the record, then the deposit skips a year and picks up again in 2008 with the year printed as the volume number.这个节奏很快就断了。2006 年在记录里只有一期，随后存录跳过一年，2008 年重新接上时卷号已经写成「2008」。
From then on the volume is the year, which makes the numbering easy to check and impossible to confuse with a count of volumes since 2005.从那以后卷号就是年份，查起来方便，也不会跟「2005 年以来出过第几卷」混起来。
Hindawi published the title from the start. The national library record still carries the Cairo imprint, with the publisher listed as Hindawi Publishing Corporation.最初由 Hindawi 出版。国家医学图书馆的记录里至今留着开罗的出版项，出版方写作 Hindawi Publishing Corporation。
Ownership moved to Springer. The records now point at Springer Nature, the journal sits on the SpringerOpen platform, and the directory entry lists a British publisher.归属后来转到 Springer。记录指向 Springer Nature，刊物落在 SpringerOpen 平台上，开放获取目录里记的出版地是英国。
Electronic deposit is short by the standard of a twenty-year journal. Crossref holds 3,107 records, and about 211 of them carry a 2025 date.对一份办了二十年的刊物来说，电子存录不算厚。Crossref 里有 3,107 条记录，其中约 211 条标着 2025 年。
The impact factor moved in a single step. It read 2.075 in 2021, 1.793 in 2022, then fell to 1 in 2023 before recovering to 1.7 and 2.3.影响因子走过一段单脚台阶。2021 年是 2.075，2022 年 1.793，2023 年掉到 1，随后回升到 1.7 与 2.3。
The five-year figure is 1.6, well below the current one, which is what a recovering title looks like in the arithmetic.五年影响因子是 1.6，明显低于当年值，这就是一份正在回升的刊物在算术上该有的样子。
The cited half-life is 6.7 years and the immediacy index is 1, so citations arrive early and keep arriving for a while.半衰期 6.7 年，即时指数 1，引用来得早，也还会持续一阵。
Ranking is stronger than the raw factor suggests. The title sits at 28 of 492 in mathematics and at 54 of 345 in applied mathematics, both first quartile.排名比原始数值好看。数学类 492 种里排第 28，应用数学类 345 种里排第 54，两个都是第一四分位。
Open access has been the model since 2005, and the gold share is 100 percent. Nothing in the journal sits behind a subscription.开放获取从 2005 年起就是模式，金色比例 100%。刊里没有内容留在订阅墙后。
The charge is 1,590 euros, or 1,990 dollars, or 1,290 pounds depending on the currency of the payer. Authors from lower-income countries can apply for a waiver.费用是 1,590 欧元，或者 1,990 美元，或者 1,290 英镑，看付款方用哪种货币结算。低收入国家的作者可以申请减免。
The medical library still lists the title as irregular and still puts it in Cairo. Both entries date from the Hindawi years and have not been revised.医学图书馆仍把这份刊物著录为不定期，也仍把它放在开罗。两条都是 Hindawi 时期留下的，没有改过。
Editors
Three editors-in-chief share the title, and they sit in three different countries. Kanishka Perera is at the Florida Institute of Technology, Vicentiu D. Radulescu at AGH University of Krakow, and Xianhua Tang at Central South University in Changsha.主编三人并列，分处三个国家。Kanishka Perera 在佛罗里达理工学院，Vicentiu D. Radulescu 在克拉科夫 AGH 大学，Xianhua Tang 在长沙的中南大学。
Under them sit 34 associate editors, and the list is short enough to read in one sitting.主编之下是 34 位副编辑，名单短到一次就能读完。
Italy and China dominate the roster. Seven associate editors come from Italian universities and more than ten from Chinese ones, with the rest spread over Poland, France, Portugal, Spain, India, Canada and Brazil.名单由意大利与中国撑起大半。七位副编辑来自意大利的大学，十余位来自中国的大学，其余散在波兰、法国、葡萄牙、西班牙、印度、加拿大与巴西。
Review is single anonymous according to the directory entry, which means the referee knows the author and the author does not know the referee.按开放获取目录的记载，评审是单匿名，也就是审稿人知道作者是谁，作者不知道审稿人是谁。
Time to publication is quoted at about thirteen weeks from acceptance. The queue that matters is the one before that, and the journal does not publish a figure for it.从录用到出版公布的是约十三周。真正要紧的是此前那一段队列，刊物对这个数字没有公布。
Two licences are offered, one plain attribution and one that bars commercial reuse and derivatives. Authors choose, and the choice is printed with the paper.许可有两种，一种只要求署名，另一种禁止商业使用与演绎。由作者挑，挑定的那一种印在论文上。
The scope is applied by judgement rather than by filter. An ESG paper and a proof of existence for a fractional problem both reached print, and the editors signed off on either.范围靠判断执行，不靠筛子。一篇 ESG 论文与一篇分数阶问题的存在性证明都印了出来，两种稿子都经编辑签过。
The masthead has one job the board cannot delegate. Someone has to decide whether a paper that uses boundary value methods in another discipline belongs in a mathematics journal, and that decision is made by a person.编委会有件事交不出去。一篇用边值方法做别的学科的论文算不算数学刊物该收的，得有人来判，判的是人。
Submissions go through the SpringerOpen platform. The journal has moved its pages to Springer Nature Link, and the old addresses redirect.投稿走 SpringerOpen 平台。刊物的页面已迁到 Springer Nature Link，旧地址会跳转。
Reviews share the queue with research papers. There is no separate section, so a review waits behind whatever was accepted before it.综述与研究论文共用一条队列。没有单独栏目，综述排在它之前录用的稿子后面。
The board's geographic spread follows the readership. Fractional calculus and nonlinear analysis grew fastest in China, Italy and Eastern Europe, and the roster records where the work is being done.编委的地理分布跟着读者走。分数阶微积分与非线性分析在中国、意大利与东欧长得最快，名单记的就是活儿在哪儿干。
Nobody on the list is paid by the journal. The editors hold university posts, and the journal's decisions rest on the time they give it.名单上没有人从刊物领薪。编辑各自在大学任职，刊物的判断立在这些人挪出来的时间上。
