Generating the mapping class group of a nonorientable surface of genus $g\ge 13$ by two elements

Abstract

Let $N_g$ be a closed, connected, nonorientable surface of genus $g$. We prove that for $g\ge 13$, the mapping class group $\text{Mod}(N_g)$ can be generated by exactly two elements. This improves the previously known bound of $g\ge 19$.
