Abstract
Our aim is to construct ordered sets and upward drawings of them to fit smooth two-dimensional surfaces using piecewise linear two-dimensional ones.
Theorem
For any smooth two-dimensional surface S of genus g there is an ordered set P such that
-
(i)
P has an upward drawing, without crossing edges, on S,
-
(ii)
P contains the ordered set crit(S) of critical points of S,
-
(iii)
if S′ is any two-dimensional surface of genus g on which P has an upward drawing, without crossing edges, then crit(S) \(\subseteq\) crit(S′).
