GAUSS Seminar

Speaker: 
Elaina Aceves
Topic: 
Comparing Bennequin-type Inequalities

Abstract:
This talk is about joint work with Keiko Kawamuro and Linh Truong that was recently posted on Arxiv. Based on the definition of the defect of the slice-Bennequin inequality defined in the work of Hamer, Ito, and Kawamuro, we introduce the defect of the $s$-Bennequin inequality and $\tau$-Bennequin inequality. We provide the first example of an infinite sequence of braids whose closures have increasing defect of the slice-Bennequin inequality but have no defect of the $s$-Bennequin inequality and $\tau$-Bennequin inequality.
