Jang-Heon Oh

Jang-Heon Oh is a Professor in the Department of Mathematics and Statistics at Sejong University, South Korea, specializing in advanced theoretical mathematics with a focus on number theory and algebraic structures.

His educational foundation includes:

• Ph.D. from Ohio State University (1995)
• M.S. from Seoul National University (1987)
• B.S. from Seoul National University (1985)

Professor Oh's research centers on Algebraic Number Theory, Iwasawa Theory, and Elliptic Curves, with seminal contributions to the computation of Iwasawa invariants, construction of anti-cyclotomic extensions, and relationships between Zeta functions and Iwasawa modules. His work bridges abstract algebra with deep arithmetic insights, particularly in the context of Galois representations and class field theory.

Analysis of his publication timeline reveals sustained expertise in p-adic methods and modular arithmetic, with recent works (2021-2022) advancing structural understanding of Zp-extensions and Iwasawa modules. His research consistently addresses foundational questions in number theory, demonstrating exceptional longevity and depth in exploring connections between algebraic invariants and analytic functions.

While no specific advising relationships or grant details appear in the source material, his h-index of 16 and 14 total publications since 1998 reflect significant scholarly influence. His professional trajectory includes postdoctoral appointments at KIAS (1996-2000) and MPIM Bonn (2001-2002), establishing a robust international research profile.
