Analysis In Theory And Applications is a prestigious academic journal with a long history, formerly known as Approximation Theory and Its Applications, published under that name from 1984 to 2002. During this period, the journal became an important platform for publishing research results in similar fields, attracting the attention and contributions of scholars and researchers worldwide. The magazine covers research achievements in various fields such as dynamic systems, geometric analysis, harmonic analysis, numerical approximation, signal analysis, special functions, differential equations, wavelets, and approximation theory. The research in these fields is not only of great significance for the development of mathematics itself, but also has extensive applications and impacts on other disciplines such as physics, engineering, computer science, etc.

In addition to publishing academic research results, the journal actively promotes the combination of theory and practical applications, encouraging scholars to apply mathematical theories to solve practical problems. The combination of theory and application has made it an interdisciplinary communication platform, attracting scholars and researchers from different fields to participate and contribute. The magazine is hosted by the Education Department of Jiangsu Province and organized by Nanjing University, with strong support and guarantee from both institutions. Under the careful organization of the editorial team, the journal has continuously improved its publication quality and academic level, becoming one of the important academic journals in the field of mathematics.
