ISU DISCRETE MATHEMATICS SEMINAR
2009-2010

Time: Tuesdays 2:10 PM       Place: 174 Carver

The Discrete Mathematics Seminar at Iowa State University is an eclectic mix of topics, including graph theory, combinatorics, linear algebra and abstract algebra. Presentations vary with the speaker and include the speaker's research, related research by others, and expository talks. Many of the expository talks (typically labeled as "Introduction to") are suitable for interested faculty and graduate students who are not specialists in the area.

For questions or to volunteer to speak in the seminar, please contact Ryan Martin or Leslie Hogben
