Pham Hoang Hiep is a Vietnamese mathematician known for his work in complex analysis.[2][3] He is a professor at the Vietnam Academy of Science and Technology and director of the International Centre for Mathematical Research and Training. He was awarded the 2015 Prof. Ta Quang Buu prize (young prize)[4][5] and the 2019 ICTP Ramanujan Prize.[2][6]

Research and career

Pham Hoang Hiep graduated from Hanoi National University of Education in 2004 and obtained his PhD at Umea University in 2008. He obtained a doctorate in science at Aix-Marseille University in 2013.[7] He is known for being the youngest full professor in Vietnam.[3][8] He is on the editorial board of Acta Mathematica Vietnamica[9]

Pham has worked on plurisubharmonic functions and (with Jean-Pierre Demailly) found a lower-bound on the log canonical threshold of such a function. If ${\displaystyle \phi }$ is such a function then Pham and Demailly found a sharp inequality on the largest constant, c, so that ${\displaystyle e^{-2c\phi }}$ is integrable in the neighbourhood of a singularity.[10][11] Pham later also worked on the "weighted log canonical threshold", which pertains to the integrability properties of ${\displaystyle f^{2}e^{-2c\phi }}$ for a fixed holomorphic function f.[12]
