Dong Han KIM

Dong Han KIM is a Professor at the Department of Mathematics Education, Dongguk University, and an Associate Member of the Korea Institute for Advanced Study. He serves as an Editor for the Bulletin of the Korean Mathematical Society. His primary research interests include Ergodic theory, dynamical systems, Metric theory of numbers, Financial mathematics, and Random number generators.

Research Contributions

• His recent work explores Diophantine approximation, particularly intrinsic approximation on circles/spheres and parity-constrained rational approximations.
• He has developed novel frameworks for Sturmian continued fractions and their Lévy constants, connecting number theory with dynamical systems.
• His Hausdorff dimension studies in inhomogeneous Diophantine approximation reveal deep metric properties of fractal sets.
• He investigates quasi-Sturmian tree colorings and Romik's dynamical system, bridging symbolic dynamics and number theory.

Scientific Collaborations

• Collaborated with leading researchers like Yann Bugeaud, Seonhee Lim, and Stefano Marmi.
• Co-authored papers with Byungchul Cha, Seul Bee Lee, and Lingmin Liao on topics spanning continued fractions to market potential models.

Academic Engagement

• Delivered invited talks at institutions across Japan, Italy, France, China, India, and Russia.
• Participated in international conferences on dynamical systems, number theory, and finance in Italy, France, China, and Singapore.
