Undergrad Diverging Gaussian curvature and (non) simply connected regions

Click For Summary
The discussion centers on the relationship between diverging Gaussian curvature (K) and simply connected regions. A key question raised is whether points where K approaches infinity indicate non-simply connected regions. One participant suggests that a surface with diverging K could feature a cusp instead of a missing point, implying that the curvature alone may not determine the connectivity of the region. The conversation highlights the complexity of linking Gaussian curvature behavior to topological properties. Understanding these relationships is crucial for deeper insights into surface geometry.

Hi there!
I have a few related questions on Gaussian curvature (K) of surfaces and simply connected regions:
  1. Suppose that K approaches infinity in the neighborhood of a point (x1,x2) . Is there any relationship between the diverging points of K and (non) simply connected regions?
  2. If K diverges in the neighborhood of a point (x1,x2), how may one prove that this point lies in a (non) simply connected region?
Thanks in advance.

I don't think so. It seems that the surface could have a cusp rather than a missing point.
