Non-existence of polyhedral immersions of triangulated surfaces in $\mathbb{R}^3$
Undine Leopold · arXiv (Cornell University) · 2016
We present and apply a method for disproving the existence of polyhedral immersions in $\mathbb{R}^3$ of certain triangulations on non-orientable surfaces. In particular, it is proved that neither of the two vertex-minimal, neighborly 9-vertex triangulations of the non-orientable surface of genus 5 are realizable as immersed polyhedral surfaces in $\mathbb{R}^3$.
