MS Seminar (Mathematics - String Theory)

Speaker: John F. Duncan (Case Western)
Title: Moonshine and Sigma Models
Date: Tue, Jun 16, 2015, 13:15 - 14:45
Place: Seminar Room A
Abstract: In the first part of the talk I will review the Conway moonshine observation of Conway--Norton, and the more recent Mathieu moonshine observation of Eguchi--Ooguri--Tachikawa. The latter of these indicates a relationship between the largest of the sporadic simple Mathieu groups and the moduli space of K3 sigma models. In the second part I will describe a vertex operator superalgebra that connects these two moonshine observations together, and partially illuminates the relationship between Mathieu's groups and K3 sigma models.
