Speaker: Dr. Nenad Vesić
Affiliation: Mathematical Institute of the Serbian Academy of Sciences and Arts, Serbia
Nenad O. Vesić was born on August 24, 1985, in Prokuplje, Serbia. He finished the elementary school and elementary music school in Prokuplje on June, 2000. During his elementary school years, he won many mathematics and physics competitions. Nenad finished the secondary school in Niš, Serbia on 2004. He was a student of Gimnazija Svetozar Marković, Department for gifted and talented mathematicians. Nenad was a participant of the Winter Mathematical Seminar in Petnica, Serbia. Nenad O. Vesić studied theoretical mathematics at Facultz of Mathematics and Sciences, University of Niš, Serbia, from October 2004 to October 2009. The title of his graduate thesis was “Inversion of Different Spaces”. At November 2009, Nenad O. Vesić started the doctoral studies at the Faculty of Mathematics and Sciences, University of Niš, Serbia. The title of his doctoral thesis was “Almost Geodesic Mappings of Generalized Riemannian Spaces and Their Generalizations”. Mathematical Institute of Serbian Academy of Sciences and Arts picked out Nenad’s doctoral thesis for one of two best in the field of mathematics and mechanics. From 2019, Nenad is employed as a researcher at the Mathematical Institute of Serbian Academy of Sciences and Arts. Nenad was awarded a scholarship by the Government of the Republic of Serbia. Today, Nenad has developed the theory of invariants for geometric mappings. He is interesting in different applications of mathematics, specially differential geometry. Physics and cryptography are Nenad’s subjects of research.
