Luen-Fai Tam

Luen-Fai Tam (Chinese: 譚聯輝, 1947 – 20 November 2025) was a mathematician working in differential geometry, general relativity, and complex geometry. He was a research professor at the Chinese University of Hong Kong.

Career Tam obtained his PhD in 1984 at Stanford University, advised by Robert S. Finn with a thesis on the behavior of capillary surfaces in low gravity.

Tam had published 96 mathematical research articles with over 1,300 citations by 546 mathematicians. His research included geometric analysis, harmonic functions, harmonic maps on complete noncompact Riemannian manifolds, mathematical relativity, and complex Kähler manifolds. According to MathSciNet, he had collaborated with 29 mathematicians, including Peter Li at UC Irvine (Tam's postdoctoral mentor while at Purdue) and Yuguang Shi at Peking University.

In honor of Tam's birthday and mathematical contributions, a conference on geometric analysis and mathematical relativity was held at Fujian Normal University in December 2018.
