Robert Johansson

Robert Johansson is an Associate Professor at the Department of Mathematics and Mathematical Statistics, Umeå University, and holds an affiliated position with the Faculty Office of Science and Technology. His research focuses on discrete mathematics and graph theory, with a strong emphasis on combinatorial structures and theoretical foundations.

Research Focus

His work explores critical areas in graph theory, including edge-decompositions, chromatic numbers, and path-factors. He has contributed to understanding extremal properties of graphs and combinatorial optimization problems in planar and r-partite graph systems.

Publications

The majority of his publications fall under discrete mathematics and theoretical computer science, with recurring themes in graph theory, combinatorial analysis, and network structures. His 2012 educational text on advanced mathematics further highlights his contributions to pedagogical frameworks.
