Publish Where Nonlinear Analysis Finds Its Voice

Letters in Nonlinear Analysis and its Applications (LNAA) isn’t just another journal. It’s a statement—a declaration that high-quality mathematics can be open, accessible, and free from the barriers that hold too many researchers back.

If you work at the frontiers of nonlinear phenomena—whether in fixed point theory, differential equations, dynamical systems, or the spaces where abstraction meets application—LNAA is built for you.

Why Publish with LNAA?

1. It’s Genuinely Free—No Fees, Ever
   No submission charges. No processing fees. No page charges. LNAA is a non-profit, open-access journal with a simple mission: to protect the quality of our community’s research without turning publication into a financial burden. In a publishing landscape where costs keep rising, LNAA stands as a practical example that “we always can do better”.
2. A Focused, Prestigious Scope
   LNAA does not try to be everything. It concentrates on what matters most in nonlinear analysis: Fixed Point Theory and Applications, Best Proximity Theory, Nonlinear Equations in Dynamical Systems, Differential Equations, Nonlinear Optimization, and Modeling of Distinction. If your work sits at these intersections, you are exactly where you belong.
3. Rapid, Regular Publication
   The journal publishes four issues per year—March, June, September, and December. That means your research reaches the community quickly and predictably, without the long waiting times that plague so many venues.
4. Led by a Global Authority
   LNAA is published by leadibng of Professor Shiego Akashi and Professor Erdal Karapınar, leading figures in nonlinear analysis and fixed point theory. Their editorial vision is simple: publish current, original, and outstanding work, and make it freely available to everyone.
5. Online, Open, and Indexed for Visibility
   As a fully online, open-access journal with eISSN 2958-874X, LNAA ensures your work is discoverable and citable. Open access means no paywalls between your ideas and the researchers who need to read them.

What We Welcome

• Original research articles that push the boundaries of nonlinear analysis.
• Selected survey papers that synthesize and illuminate emerging directions.
• Technical notes that deliver precise, significant contributions.

All submissions undergo rigorous peer review. Quality is never compromised—only access is widened.
