About this journal

Demonstratio Mathematica is a fully peer-reviewed, open access, electronic journal devoted to functional analysis, approximation theory and related topics. The journal presents a forum where all aspects of these problems can be discussed. The journal provides the readers with free, instant, and permanent access to all content worldwide; and the authors with extensive promotion of published articles, long-term preservation, no space constraints and quick online publication.

Demonstratio Mathematica is listed inter alia by Web of Science (ESCI), SCOPUS, MathSciNet and zbMATH. Our standard policy requires each paper to be reviewed by at least two Referees and the peer-review process is single-blind.

The potential topics include (but are not limited to):

Approximation theory and iteration methods
Fixed point theory and methods of computing fixed points
Functional, ordinary and partial differential equations
Nonsmooth analysis, variational analysis and convex analysis
Optimization theory, variational inequalities and complementarity problems

For more detailed list of the potential topics please refer to Instruction for Authors.

The journal considers submissions of different types of articles. "Research Articles" are focused on fundamental theoretical aspects, as well as on significant applications in science, engineering etc. “Communications” are intended to present information of exceptional novelty and exciting results of significant interest to the readers. “Review articles” and “Commentaries”, which present the existing literature on the specific topic from new perspectives, are welcome as well.

Demonstratio Mathematica is subject to an Article Processing Charge (APC). There are no submission charges – Article Processing Charges apply after the acceptance of a manuscript. Authors, who have limited access to funds, may request for a discount. Inquiries concerning APCs should be addressed before or immediately after submission of a paper to the Editorial Office (demonstratio.editorial@degruyter.com). For more details please refer to Article Processing Charges document (in PDF).
