Theory of minimal surfaces has always been in the center of differential geometry. The most difficult part in minimal surfaces is how to find meaningful examples. In this paper we survey the history of search for minimal surfaces. We also introduce examples of recently emerging maximal surfaces in the Lorentz-Minkowski space and compare the processes in the search for the minimal and the maximal surfaces.

In the present study, we investigate and compare the International Mathematical Olympiad participation histories of Korea, China, and Japan. Especially, the processes for the first participation of the IMO, trends in team rankings of the IMO, and national team selection systems and education systems are compared. And we investigate and compare the policies for the talented girls mathematics Olympians. Several proposals are suggested for development of Korean Mathematical Olympiad and participations to IMO.

In the present study, we review the history of the participations of the Korean national team in the International Mathematical Olympiad for 28 years. We identifiy three major events that highlighted the development of the Korean Mathematical Olympiad program: The first participation in the International Mathematical Olympiad, hosting of the International Mathematical Olympiad, and winning the first place in the International Mathematical Olympiad. We also propose some recommendations for next steps to facilitate the development of Mathematical Olympiad in Korea.
