Title: A short proof of a forgotten result
Speaker: | Bertrand Guenin |
Affiliation: | University of Waterloo |
Room: | MC 4042 |
Abstract:
In 1982 Shih characterized in her Phd thesis the exact relationship between a graph and a signed graph when the cycle space of the graph is equal to the even cycle space of the signed graph. This is a beautiful result that has not received the attention it deserves. One reason is that the result was never published in a refereed journal and that the original proof was very long and technical. I will present a much shorter proof of this result. This is joint work with Zouhaier Ferchiou.

The University of Waterloo acknowledges that much of our work takes place on the traditional territory of the Neutral, Anishinaabeg and Haudenosaunee peoples. Our main campus is situated on the Haldimand Tract, the land granted to the Six Nations that includes six miles on each side of the Grand River. Our active work toward reconciliation takes place across our campuses through research, learning, teaching, and community building, and is centralized within our Office of Indigenous Relations.
