Aims & Scope

About the Journal Aims and scope Founded in 1972, Journal of Numerical Analysis and Approximation Theory publishes original papers presenting rigorous analysis, numerical methods with theoretical results (accuracy, convergence, stability), computational examples, development and implementation of numerical algorithms, and the interplay between these aspects for topics such as: differential equations (ordinary and partial), optimization, control theory, inverse problems, nonlinear equations and systems, iterative methods, numerical linear algebra, applied functional analysis, approximation theory, interpolation, mathematical aspects of neural networks and machine learning, mathematical modeling, scientific computing. Papers dealing with iterative methods in \(\mathbb{R}^n\), accompanied by numerical applications, are preferred to settings in \(\mathbb{R}\) or abstract spaces (with no concrete applications indicated). Applications and strong connections to the aspects mentioned above are mandatory for papers whose main topics concern, for example, inequalities, fractional equations, fuzziness. It is recommended that original papers do not exceed 25 pages in length. Reproducibility: Authors should include sufficient information in the manuscript to enable the results of the manuscript to be reproduced. It is recommended to include an online repository containing relevant software and data. The journal also publishes survey papers in all areas of Numerical Analysis and Approximation Theory, recommended not to exceed 40 pages. Journal of Numerical Analysis and Approximation Theory is a single-blind peer-reviewed journal. It considers for publication only papers written in English. There are no publication fees. Its former name is Revue d'Analyse Numérique et de Théorie de l'Approximation (see the history section). All the papers are freely available at the archives section, either scanned (1972-2000), or latex-pdf (since 2001). The journal is edited by Tiberiu Popoviciu
