DESCRIPTION

This thematic special issue in Demonstratio Mathematica is focused on the Ulam stability of equations and Ulam stability of operators.

Potential topics include, but are not limited to, Ulam stability of:

  • functional equations
  • difference equations
  • differential and integral equations
  • linear operators
  • operators of polynomial form

We also invite papers on connections between fixed point theory and Ulam stability.

There will be two parts of this special issue. The Part II will be particularly devoted to the publication of high-quality research papers presented during 3rd Conference on Ulam's Type Stability (https://cuts.up.krakow.pl/2018/), held in Timișoara, Romania, October 8-13, 2018.

The authors are requested to submit their full revised version of papers complying with the general scope of this thematic special issue. The submitted papers will undergo peer review process before they can be accepted. Notification of acceptance will be communicated as we progress with the review process.

HOW TO SUBMIT

Before submission authors should carefully read the Instruction for Authors, available online at:
https://www.degruyter.com/view/supplement/s23914661_Instruction_for_Authors.pdf

Manuscripts should be written in LATEX, AMS-TEX, AMS-LATEX. We do not accept papers in Plain TEX format. If, additionally, a PDF file is supplied, the peer review process will be speed up. Authors are encouraged to submit the final version of the paper using the De Gruyter LATEX template.

All submissions to the Special Issue must be made electronically via online submission system Editorial Manager (http://www.editorialmanager.com/dema/) and will undergo the standard peer-review process (single blind, at least two independent reviewers). When entering your submission choose the option “TI on Ulam Stability” as an article type.

Contributors to this thematic special issue will benefit from:

  • indexation in Web of Science Core Collection (Emerging Sources Citation Index) and SCOPUS
  • fair and constructive peer review provided by experts in the field
  • no space constraints
  • convenient, web-based paper submission and tracking system – Editorial Manager
  • language assistance for authors from non-English speaking regions
  • fast online publication upon completing the publishing process
  • better visibility due to Open Access
  • long-term preservation of the content (articles archived in Portico)

The deadlines for submission to the Topical Issue are as follows:
Part I:  June 30, 2018 (publication in 2018)
Part II:  February 10, 2019 (publication in 2019)

Individual papers will be reviewed and published online on an ongoing basis.

In 2018 Demonstratio Mathematica offers 50% discount to all the authors − the publication fee amounts to 500 Euro per paper, regardless of its length.
Additionally, fees for authors who have limited access to funding for publications may be further reduced. Inquiries concerning Article Processing Charges should be addressed before or immediately after submission of a paper to the Managing Editor of the journal (Justyna.Zuk@degruyter.com).
