Tan Lei (Chinese: 谭蕾) was a mathematician specialising in complex dynamics and functions of complex numbers. She is most well-known for her contributions to the study of the Mandelbrot set and Julia set.[1]
Career
After gaining her PhD in Mathematics in 1986 at University of Paris-Sud, Orsay, Tan worked as an assistant researcher in Geneva. She then conducted postdoctoral projects at the Max Planck Institute for Mathematics and University of Bremen until 1989, when she was made a lecturer at Ecole Normale Superieure de Lyon in France. Tan held a research position at University of Warwick from 1995 to 1999, before becoming a senior lecturer at Cergy-Pontoise University. She was made professor at University of Angers in 2009.[2]
Mathematical work
Tan obtained important results about the Julia and Mandelbrot sets, in particular investing their fractality and the similartities between the two.[pub 1] For example she showed that at the Misiurewicz points these sets are asymptotically similar through scaling and rotation.[pub 2] She constructed examples of polynomials whose Julia sets are homeomorphic to the Sierpinski gasket[pub 3] and which are disconnected.[pub 4] She contributed to other areas of complex dynamics.[pub 5][pub 6] She also wrote some surveys and popularisation work around her research topics.[pub 7][pub 8]
Legacy
A conference in Tan's memory was held in Beijing, China, in May 2016.[3]
