A Themed Issue on Mathematical Inequalities, Analytic Combinatorics and Related Topics in Honor of Professor Feng Qi

Dear Colleagues,

Professor Feng Qi received his Ph.D. degree from the University of Science and Technology of China in 1999 and is currently a full Professor at Tiangong University and Henan Polytechnic University, China. He was invited to visit Victoria University in Australia and the University of Hong Kong twice for academic collaborations, and he was invited to visit the University of Copenhagen, Denmark; Antalya Bilim University in Turkey; several universities in South Korea; Sun Yat-sen University, China; and Kaohsiung Normal University, China for conferences, special lectures, or other academic activities. He is or was the editor-in-chief, an associate editor, or a member of the editorial board of about 40 reputable international journals. Since 1993, he has published over 660 papers in 215 journals, collections, or proceedings. He took charge of and participated in two national research projects supported by the National Natural Science Foundation of China and several provincial scientific projects supported by Henan Province in China. Since 1992, he has acquired about one and a half millions CNY of funding support. In Stanford University’s 2021 list of World’s Top 2% Scientists, among 190,064 scientists in the Single Year Impact Data (2020), he ranked 61,510 and, among 186,178 scientists in the Career-long Data (1960–2020), he ranked 96,040. In the 2022 edition of the World's Top Mathematics Scientists by Research.com, he currently ranks 329. Currently, his academic interests and research fields mainly include the theory of special functions, classical analysis, mathematical inequalities and applications, mathematical means and applications, analytic combinatorics, analytic number theory, etc. 

The purpose of this Special Issue is to pay tribute to the significant contributions made by Professor Feng Qi in these fields and to provide some important recent advances in theory, methods, and applications. We cordially and earnestly invite researchers to contribute their original and high-quality research papers, which will inspire more advances in mathematical inequalities, number theory, combinatorics, nonlinear analysis, optimization, and their applications. Potential topics include but are not limited to the following:

• Mathematical inequalities and applications;
• Mathematical means and applications;
• The theory of special functions;
• Analytic combinatorics;
• Analytic number theory;
• Nonlinear functional analysis;
• Optimization;
• Convex analysis of functions;
• Matrix theory.
