Nonlinear Convex Analysis and Optimization: An International Journal on Numerical, Computation, and Applications is a journal entirely devoted to nonlinear convex analysis, optimization, and its applications. Especially, in the year 2020, the 60th anniversary KMUTT and the 5th of the Center of Excellence in Theoretical and Computational Science (TaCS-CoE) become form TaCS-Center, KMUTT. This center started in 2014 at the initiative and under the guidance of Professor Sompong Dhompongsa. The yearly publication of the symposium was the International Symposium on Nonlinear Convex Analysis and Optimization (since 2018). The Journal on Nonlinear Convex Analysis and Optimization (since 2020) are continuations of this publication.
The International Symposium on Nonlinear Convex Analysis and Optimization 2020 (NCAO2020) is the third of its series organized annually by the Center of Excellence in Theoretical and Computational Science Center (TaCS-CoE). The second International Symposium on Nonlinear Convex Analysis and Optimization 2019 (NCAO2020) is the second of its series organized annually by the NCAO-Research Center and Theoretical and Computational Science Center (TaCS Center) held during September 4-6, 2019, Also in this year, we have a Satellite even to A Seminar on Topics and Trends in Fixed Point Theory and Applications on September 11-11, 2019. The first event, NCAO2018, held during July 19-22, 2018, was a big success in the goal of bringing together leading international experts in nonlinear and convex analysis for exclusive and intensive lectures.
In 2018, The first International Symposium on Numerical Convex Analysis and Applications (NCAO) was organized in KMUTT and due to its great success, we henceforth tried to organize the same event every year with an aim to bring together the researchers and enthusiasts in this specific topic. Due to the COVID-19 pandemic and Thai government safety measures, the previous and present NCAO (2020 and 2021 respectively) were forced to be an online event. In 2020, the NCAO2020 aims at bringing together the outstanding mathematicians in the areas related to optimization, variational inequality, equilibrium theory, Numerical optimization, Computation fixed point and Nash games in both theoretical and applied perspectives.
In 2021, we organize The 4th NCAO 2021 with two interesting and in-fashion themes of convex analysis, namely fixed point theory and geodesic convex analysis.
All invited speakers will be invited as Editorial Board Members of the journal.
