## The 2-width of 3-manifolds embedded in $\mathbb{R}^4$

##### Abstract:

Morse theory can be generalized to the study of maps to $R^k$. I will discuss where this leads, focusing on ambient Morse functions of embedded 3-manifolds. The relevance to the question of finite generation of the Goeritz groups $G_g$ will be explained.
