Stevo Todorčević

Stevo Todorčević (Стево Тодорчевић; born February 9, 1955), is a Yugoslavian mathematician specializing in mathematical logic and set theory. He holds a Canada Research Chair in mathematics at the University of Toronto,  and a director of research position at the Centre national de la recherche scientifique in Paris.

Early life and education
Todorčević was born in Ubovića Brdo. As a child he moved to Banatsko Novo Selo, and went to school in Pančevo. At Belgrade University, he studied pure mathematics, attending lectures by Đuro Kurepa. He began graduate studies in 1978, and wrote his doctoral thesis in 1979 with Kurepa as his advisor.

Research
Todorčević's work involves mathematical logic, set theory, and their applications to pure mathematics.

In Todorčević's 1978 master’s thesis, he constructed a model of MA + ¬wKH in a way to allow him to make the continuum any regular cardinal, and so derived a variety of topological consequences. Here MA is an abbreviation for Martin's axiom and wKH stands for the weak Kurepa Hypothesis. In 1980, Todorčević and Abraham proved the existence of rigid Aronszajn trees and the consistency of MA + the negation of the continuum hypothesis + there exists a first countable S-space.

Awards and honours
Todorčević is the winner of He was selected by the Association for Symbolic Logic as their 2016 Gödel Lecturer.
 * the first prize of the Balkan Mathematical Society for 1980 and 1982,
 * the 2012 CRM-Fields-PIMS prize in mathematical sciences, and
 * the Shoenfield prize of the Association for Symbolic Logic for "outstanding expository writing in the field of logic" in 2013, for his book Introduction to Ramsey Spaces.

He became a corresponding member of the Serbian Academy of Sciences and Arts as of 1991 and a full member of the Academy in 2009. In 2016 Todorčević became a fellow of the Royal Society of Canada.

Todorčević has been described as "the greatest Serbian mathematician" since the time of Mihailo Petrović Alas.
