Open Access Policy
International Journal of Nonlinear Science (IJNS) is committed to ensuring that high-quality research in nonlinear science, applied mathematics, computational science, engineering, and interdisciplinary research is freely accessible to the global scientific community. IJNS embraces the principles of open access to maximize the visibility, dissemination, and impact of scholarly research by removing barriers to knowledge exchange and fostering worldwide scientific collaboration.
Open access at IJNS is founded on the belief that scientific knowledge should be available to researchers, educators, practitioners, policymakers, and industry professionals without financial or institutional restrictions. By providing unrestricted access to published research, IJNS promotes the rapid dissemination of theoretical developments, computational innovations, numerical methods, and practical applications in nonlinear science. This approach accelerates scientific discovery, encourages interdisciplinary collaboration, and supports evidence-based innovation across mathematics, physics, engineering, computer science, management, economics, and other related disciplines.
All articles published in the IJNS are made permanently available online immediately upon publication. Readers worldwide may freely access, read, download, share, distribute, and cite published articles without subscription fees, ensuring that research remains widely discoverable and continues to contribute to scientific advancement and technological innovation for years to come.
To support the editorial and publishing processes, including rigorous peer review, professional copyediting, typesetting, digital production, long-term preservation, website maintenance, and indexing services, IJNS applies an Article Processing Charge (APC) to accepted manuscripts. The APC becomes payable only after a manuscript has successfully completed peer review and has been formally accepted for publication, ensuring that editorial decisions are based solely on academic merit, originality, scientific quality, and relevance to the journal’s scope.
Authors are encouraged to consult their universities, research institutions, funding agencies, or sponsoring organizations regarding financial support for open access publishing, as many institutions provide dedicated funding or agreements to cover publication charges.
To ensure the long-term accessibility and integrity of published research, every article published in IJNS is assigned a Digital Object Identifier (DOI), providing a permanent and reliable citation record. IJNS is committed to the long-term preservation and discoverability of its published content through recognized digital archiving services and international indexing platforms, thereby enhancing global visibility, accessibility, and citation potential.
IJNS views open access not merely as a publishing model, but as a commitment to scientific transparency, academic excellence, and the unrestricted exchange of knowledge. By making cutting-edge research freely available to the international research community, IJNS seeks to accelerate scientific progress, encourage interdisciplinary innovation, strengthen collaboration between academia and industry, and advance the understanding and application of nonlinear science across diverse scientific, engineering, technological, and management disciplines.
