Bálint Érdi was born on March 30, 1945, in Esztergom, Hungary, and graduated in mathematics, physics, and astronomy teaching at Eötvös Loránd University in 1968. He joined the university’s Department of Astronomy the same year and served as its head from 1998 to 2009. An expert in celestial mechanics, his research spans traditional and modern methods, particularly the dynamics of Trojan asteroids. He has supervised numerous academic works, published extensively, and received international recognition, including having the asteroid (241363) Erdibalint named in his honor.

Meeting Scope

We are organizing an international scientific conference titled The Art of the Invisible Force: the Dynamics of Equilibria Near and Far (Scientific Conference in Honor of Bálint Érdi)" to celebrate Professor Bálint Érdi's 80th birthday. Professor Emeritus Bálint Érdi was born on March 30, 1945, in Esztergom, Hungary. He graduated from Eötvös Loránd University (ELTE) and worked at the university's Department of Astronomy.
