Yu JaeHyun, professor in the Department of Mathematics, was selected on October 23 (Thu) for the 17th POSCO Science Fellowship.
The POSCO Science Fellowship, operated by the POSCO TJ Park Foundation, is a program designed to identify and support promising early-career researchers with outstanding achievements in basic and applied sciences in Korea. Launched in 2009 with the aim of establishing the importance of basic science and fostering scientific talent, the program selects young and capable scientists working in basic and applied science fields in Korea and provides two years of funding totaling 100 million KRW. It has become known as the “rookie award of the science community,” particularly because it offers crucial support for young researchers who may lack sufficient external funding as they begin independent research or experiments. This year, 30 fellows were selected from a highly competitive pool, with the acceptance rate exceeding 13 to 1.
Joining the Department of Mathematics at Ewha Womans University this March, Professor Yu JaeHyun is a specialist in harmonic analysis, a field that studies functions by interpreting them as superpositions of waves with various frequencies and analyzing their frequency characteristics. His research focuses on uncovering properties of oscillation and convergence of functions using fundamental mathematical tools such as the Fourier transform and Fourier series.
Professor Yu’s research team continues to investigate how precisely functions converge and to explore the mathematical properties of maximal operators. Such research not only contributes to addressing classical open problems in harmonic analysis but also provides essential theoretical foundations for understanding oscillatory and convergence behaviors of functions. Moreover, these findings can be applied to understanding principles of data interpretation in diverse fields such as signal processing, physics, and artificial intelligence, demonstrating both academic and practical value.
