Ewa Maria Kubicka is a Polish mathematician interested in graph theory and actuarial science.[1] She is known for introducing the concept of the chromatic sum of a graph, the minimum possible sum when the vertices are labeled by natural numbers with no two adjacent vertices having equal labels.[2]
Kubicka studied mathematics at Wrocław University of Science and Technology beginning in 1974, and earned a master's degree there in 1979. She came to Western Michigan University for graduate study, earning both a master's degree in computer science and a Ph.D. in mathematics in 1989.[1] Her dissertation, The Chromatic Sum and Efficient Tree Algorithms, was supervised by Allen J. Schwenk.[3] She became an assistant professor at Emory University and then, in 1990, moved to the University of Louisville, where she has been a full professor since 2004.[1] At Louisville, she directs the actuarial program and is undergraduate advisor for mathematics.[4]
She is known for having an erdős number of one.[5]
