Alexandre Eremenko
Alexandre Emanuilovych Eremenko is a Ukrainian-American mathematician who works in the fields of complex analysis and dynamical systems.
Academic career
Eremenko was born into a medical family in Kharkiv, Ukraine. His father was a pathophysiologist, professor and head of the Department of pathophysiology at Ternopil National Medical University. His mother was an ophthalmologist. He obtained his master's degree from Lviv University in 1976 and worked in the Institute of Low temperature physics and Engineering in Kharkiv until 1990. He received his PhD from Rostov State University in 1979 , and is currently a distinguished professor at Purdue University.In complex dynamics, Eremenko explored escaping sets at the iteration of transcendental entire functions and conjectured that the connected components of this escaping set are unbounded . For decades, the conjecture remained open, and has been called "one of the most famous open problems in transcendental dynamics"; a counterexample has been found in the 2020s.
