Preface: Mathematical problems in science, engineering and aerospace

Abstract

In its broadest sense, mathematical analysis encompasses a significant segment of mathematics. The subject matter encompasses various mathematical disciplines such as variational calculus, differential geometry, functional analysis, harmonic analysis, approximation theory, ordinary differential equations, partial differential equations, integral equations, theory of functions of real and complex variables, and approximation theory.

Modern number theory and probability theory both use and develop methods of mathematical analysis. It is applicable to a wide range of fields, including as engineering, economics, and biology. In this connections,world congress --- the 13th International Conference on Mathematical Problems in Engineering, Aerospace and Sciences was held during June 2023.
This conference's primary goal is to bring together senior and junior academics who work in mathematical analysis and related fields of science and engineering so they can share novel concepts and tackle today's pressing problems. Research articles in the wide topic of mathematical analysis with applications in engineering and applied sciences are included in this special issue. Extended versions of a few selected papers that were given at the Conference (2023 ICNPAA World Congress \ http://www.icnpaa.com/index.php/icnpaa/ICNPAA2020), in Prague, Czech Republic, as well as a few invited contributions, are included in this special issue.
