from Wikipedia, the free encyclopedia

Bojan Mohar (born September 21, 1956 in Novo mesto ) is a Slovenian mathematician who deals with graph theory.

biography

Mohar received his doctorate in 1986 under Tomaz Pisanski at the University of Ljubljana and is a professor at the University of Ljubljana. He has also held a Canada Research Chair at Simon Fraser University since 2005 .

Mohar deals with topological graph theory (e.g. graphs on surfaces, planar graphs), graph minors , graph coloring (including Nowhere-zero flows), graph algorithms and algebraic graph theory ( eigenvalues ​​of the Laplace operator on graphs , spectra of infinite graphs). He is researching a comprehensive theory of the geometric embedding of graphs. He also deals with applications of graph theory in chemistry ( Wiener index ).

He was visiting scholar at the Technical University of Denmark , TU Ilmenau , Simon Fraser University , McGill University , Georgia Institute of Technology and EHESS in Paris.

In 1988 he received a Fulbright scholarship, in 2004 he received the Slovenian Boris Kidrič Prize and in 2010 the Euler Medal . In the laudation for the Euler Medal, he was recognized as one of the world's leading mathematicians in the field of discrete mathematics. In 2018 he became a SIAM Fellow and received the John L. Synge Award . He is a member of the Slovenian Engineering Academy. In 2009 he became Ambassador for Science in Slovenia.

He is one of the main editor of the Journal of Combinatorial Theory B .
