Welcome to the
Electronic Journal of Qualitative Theory of Differential Equations

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 1.1. 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. EJQTDE is covered by the Mathematical Reviews, Zentralblatt, Scopus, DOAJ, and EBSCO. The journal's content is indexed in Science Citation Index, Current Contents and Journal Citation Reports. EJQTDE 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 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.

We want to thank the Free Journal Network for promoting fair open access journals.
