Abstract:

I will discuss some aspects of the definition and calculation of the genus of a surface. These are mainly some things that I learned in the course of teaching MTH 333 last fall. I will also share an evocative proof of the Jordan Separation Theorem due to R. Maehara (Amer. Math Monthly 91 (1984), 631-634) that I found while teaching MTH 532 this past winter. The Jordan Separation Theorem is related to the role of genus in the classification of surfaces.
