According to the proposal of the editor-in-chief of the Journal of Fourier Analysis and Applications (JFAA), Professor Hans Feichtinger, there is an initiative group of editors in the direction of Operator Theory, specifically related to Harmonic Analysis and Applications.

**This thematic direction will include articles at the cross-road of operator theory and harmonic analysis.**

To be more precise, we expect to deal with papers related to the**Interplay of "Harmonic Analysis" and "Operator Theory", covering applications of Fourier (harmonic) analysis and operator theory** arising in problems of mathematical physics and PDE's, inverse problems; models of mathematical physics; related questions of applied math / computational math.

To be more precise, we expect to deal with papers related to the

Professor Stefan Samko – 80th Jubilee

According to the proposal of the editor-in-chief of the Journal of Fourier Analysis and Applications (JFAA), Professor Hans Feichtinger, there is an initiative to publish a special issue(provisionally) titled "Operator Theory and Fourier Analysis" dedicated to the 80 anniversary of**Professor Stefan Samko**.

We expect high quality papers closely related to the topics of Fourier analysis, Harmonic analysis and Operator theory including the applications of the above mentioned fields in PDE's and mathematical physics.

We expect high quality papers closely related to the topics of Fourier analysis, Harmonic analysis and Operator theory including the applications of the above mentioned fields in PDE's and mathematical physics.

- The typical size of a paper should be between 10 and 25 pages, including figures.
- We propose the end of August 2021 as a deadline, but the manuscripts will go into the review process as soon as they are received. We will make an attempt to finish the review process by the end of the year.
- Professor Hans Feichtinger has agreed to be ready for consultation in case someone is not sure about the topic to be chosen for the contribution.
- According to JFAA habits
**we try to avoid one author having more than one authorship within a year**, so as to give everybody a chance to publish with JFAA.

In accordance with the proposal of the Presidential Advisor of Pleiades Publishing, Ltd. Nikolay Avanesov and editor in chief of Journal of Applied and Industrial Mathematics (https://www.springer.com/journal/11754) Professor Vladimir Beresnev, within the framework of OTHA-ISAAC research group supported by the international society ISAAC, editorial thematic section OTHA-JAIМ (otha.sfedu.ru) has been established.

**Journal overview** (more details at https://www.springer.com/journal/1175):

Journal of Applied and Industrial Mathematics is a journal that publishes original and review articles containing theoretical results and those of interest for applications in various branches of industry. The journal topics include the qualitative theory of differential equations in application to mechanics, physics, chemistry, biology, technical and natural processes; mathematical modeling in mechanics, physics, engineering, chemistry, biology, ecology, medicine, etc.; control theory; discrete optimization; discrete structures and extremum problems; combinatorics; control and reliability of discrete circuits; mathematical programming; mathematical models and methods for making optimal decisions; models of theory of scheduling, location and replacement of equipment; modeling the control processes; development and analysis of algorithms; synthesis and complexity of control systems; automata theory; graph theory; game theory and its applications; coding theory; scheduling theory; and theory of circuits. Description of the thematic section

I) The thematic section of OTHA-JAIM initiative is focused on research and applied research articles where applied and harmonic analysis and also methods of mathematical physics, theory of operators and theory of equations in partial derivative represent the fundamental basement for results, methods and applications.

II) Articles in the field of signal processing, data transmission and reconstruction, image identification, mathematical medicine, articles on bioinformatics and mathematical modeling in medicine and biotechnologies, articles using probabilistic and analytical methods and models are particularly welcome

III) The article should meet the journal requirements, besides, the article's scientific novelty and scientific significance and its correspondence to the thematic section must be obvious. The results cannot be published by any other publishing house. In case of an overview character of the article it should be clearly specified in the introduction and abstract of the article.

The following will not be considered within the frames of the given initiative:

1. Scientific applied articles, with mainstays (fundamental basement) other then in fields mentioned above. It is appropriate to send these articles directly to the journal with no reference to OTHA-JAIM initiative.

2. Articles based on well-known applied methods and algorithms only, or based entirely on numerical experiment and calculations, and also containing only experimental results without any following application, theoretical and fundamental conclusions and arguments.

3. Articles which do not comply with the level and requirements of the journal, scholarly, educational and methodological articles. The articles which earlier have not been accepted by JAIM, and those with conflict of interests. Articles with four and more authors may become a subject for discussion of authors' input before admission to consideration.

**Article submission procedure:**

Please send your articles in PDF to**Elena Vasilyeva-Bagler** (Editorial Assistant) to the following address: otha.editorial@gmail.com

You may also send your questions to the email address given above or directly to editors.
