Important Notice: IJAM Website Migration
We are pleased to inform you that the International Journal of Applied Mathematics (IJAM) has officially migrated to a new website with an improved interface and editorial management system.

đź”— New Website URL: https://ijamjournal.org/ijam
📬 New Submission & Contact Email: editor@ijamjournal.org

🗓️ Effective from 15 May 2025, all future issues, submissions, and editorial activities will be managed through the new platform. Authors, reviewers, and readers are kindly requested to visit the new website for:
• New submissions, • Journal policies, • Editorial board information, • Access to new and upcoming issues.
📚 Note:All previous issues will remain accessible at https://www.diogenes.bg/ijam for archival purposes. However, Issue No. 3 of Volume 38 (2025) and all future publications will appear only on the new website https://ijamjournal.org/ijam
We appreciate your continued support and cooperation during this transition.
For any queries, please contact us at: editor@ijamjournal.org

Journal’s details:

Topics:combinatorics, design and configurations, graph theory, fractals, lattices, ordered algebraic structures, real functions, measure and integration, functions of complex variable, potential theory, special functions, fractional calculus, operational calculus and integral transforms, dynamical systems in their broadest sense (covering ODEs, all kinds of PDEs, FDEs, difference equations, functional equations), approximation and expansion, integral equations, operator theory, calculus of variations, optimal control, optimization, applied differential geometry, probability theory and stochastic processes, statistics, numerical analysis, computer science, mechanics of particle and systems, mechanics of solids, fluid mechanics, classical thermodynamics, mathematical methods in economics, operations research, programming, mathematical biology, systems theory, information and communication, circuits.

Submissions: Only LaTeX typeset manuscripts can be considered. Submissions should be sent by e-mail to Managing Editor at editor@ijamjournal.org, please initially send pdf-file and cover letter. After acceptance, the manuscripts should be obligatory prepared strictly in the IJAM style and format (use LATEX SAMPLE, LATEX SAMPLE (TEX file) and LATEX SAMPLE (PDF file)). Authors will need then to provide the LaTeX-, pdf- and figures files (in eps- or pdf-formats) in finally revised form, accompanied a signed copyright form. All queries should be addressed to Managing Editor, see CONTACT US.

Frequency: To ensure timeliness of publication, we have 6 issues per year, each 2 months.

Open Access: The journal has Open Online Access to contents of published issues and to full text papers (since 2012), with assigned DOI-number to each paper and link to CrossRef. Minor APC (Article Processing Charges) may apply for authors or their supporting institutions to cover publisher’s expenses for maintaining its server and journal’s website, prices for DOIs numbers, printing hardcopy issues for some basic libraries, etc.

Indexation: IJAM is indexed in Scopus (Elsevier) – since Vol. 30 (2017) and on, with current impact rang SJR = 0.304 (2024) in Q3, details:
