Electronic Journal of Qualitative Theory of Differential Equations

《微分方程定性理论电子期刊》(EJQTDE)由T. A. Burton和L. Hatvani于1998年创办。从那时起，我们得出该期刊的影响因子为0.881(5年影响因子为0.992)。我们感谢我们的作者和编辑的成功。《微分方程定性理论电子期刊》(EJQTDE)致力于为您提供高质量的微分方程定性理论论文。在EJQTDE中出现的论文以PDF格式提供，可以预览或下载到您的计算机中。EJQTDE由数学评论Zentralblatt和Scopus覆盖。汤森路透产品和定制信息服务也选择了它，这意味着它的内容在科学引文索引、当前内容和期刊引文报告中都有索引。我们的期刊有国际标准编号胡士恩1417-3875。所有与微分方程定性理论(稳定性、周期性、有界性等)相关的主题(ODE’s、PDE’s、积分方程、泛函微分方程等)及其应用都将考虑出版。研究论文的评审标准与数学评论所涵盖的任何印刷期刊的评审标准相同。长篇论文和会议记录可作为专著接受编辑的自由裁量权。《微分方程定性理论电子期刊》每3-4年出版一次博莱研究所主办的微分方程定性理论学术研讨会论文集。《微分方程定性理论电子期刊》是一本开放获取的期刊，它意味着所有的内容都是免费提供给用户或他/她的机构的。未经出版商或作者事先许可，用户可以阅读、下载、复制、分发、打印、搜索或链接到文章的全文，或将文章用于任何其他合法目的。这符合BOAI对开放获取的定义。出版也不收取任何费用。

The Electronic Journal of Qualitative Theory of Differential Equations (EJQTDE) was founded by T. A. Burton and L. Hatvani in 1998. Since then we achieved that this journal has an impact factor of 0.881 (5-year impact factor: 0.992). We thank this success to our authors and editors.The Electronic Journal of Qualitative Theory of Differential Equations (EJQTDE) is dedicated to bringing you high quality papers on the qualitative theory of differential equations. Papers appearing in EJQTDE are available in PDF format that can be previewed, or downloaded to your computer. The EJQTDE is covered by the Mathematical Reviews, Zentralblatt and Scopus. It is also selected for coverage in Thomson Reuters products and custom information services, which means that its content is indexed in Science Citation Index, Current Contents and Journal Citation Reports. Our journal has the International Standard Serial Number HU ISSN 1417-3875.All topics related to the qualitative theory (stability, periodicity, boundedness, etc.) of differential equations (ODE's, PDE's, integral equations, functional differential equations, etc.) and their applications will be considered for publication. Research articles are refereed under the same standards as those used by any printed journals covered by the Mathematical Reviews. Long papers and proceedings of conferences are accepted as monographs at the discretion of the editors. The Electronic Journal of Qualitative Theory of Differential Equations will publish the proceedings of the Colloquium of Qualitative Theory of Differential Equations organized by the Bolyai Institute every 3-4 years.The Electronic Journal of Qualitative Theory of Differential Equations is an open access journal which means that all content is freely available without charge to the user or his/her institution. Users are allowed to read, download, copy, distribute, print, search, or link to the full texts of the articles, or use them for any other lawful purpose, without asking prior permission from the publisher or the author. This is in accordance with the BOAI definition of open access. There are no charges and fees for publication, either.
