Margit Voigt
Margit Voigt is a German mathematician specializing in graph theory and graph coloring. She is a professor of operations research at the University of Applied Sciences Dresden.[1]
Voigt completed her Ph.D. in 1992 at the Technische Universität Ilmenau. Her dissertation, Über die chromatische Zahl einer speziellen Klasse unendlicher Graphen [On the chromatic number of a special class of infinite graphs] was jointly supervised by Rainer Bodendiek and Hansjoachim Walther.[2]
Her results include the first known planar graph that requires five colors for list coloring,[3][4][5] and a counterexample to a related conjecture that list coloring of planar graphs requires at most one more color than graph coloring for the same graphs.[3]
