Two distinguished mathematicians are set to visit UW-Superior this fall to speak about problems and research in discrete mathematics.

Dr. Jerrold Griggs, the Carolina Distinguished Professor at the University of South Carolina, is expected on campus for several days in November.

Dr. Gyula Katona, who is affiliated with the Alfréd Rényi Institute of Mathematics of the Hungarian Academy of Sciences, is expected to be on campus for three days in late November.

The mathematicians accepted invitations to visit UW-Superior because they are acquainted with members of the faculty in the Department of Mathematics and Computer Science.

Their visit will benefit students by enabling them to attend talks by world-class researchers, said Dr. Sergei Bezroukov. The visiting professors' talks will be open to the public.

Dr. Griggs received his doctorate degree in applied mathematics from Massachusetts Institute of Technology in 1977. His research interests include combinatorics, extremal set theory, extremal graph theory, graph coloring, operations research, as well as applications of discrete math to biology, number theory, analysis of algorithms, and communications.

Dr. Katona is known for his work in combinatorial set theory, and especially for the Kruskal-Katona theorem and his elegant proof of the Erd's-Ko-Rado theorem.
