Simply connected domain

Summary

A simply connected domain is a path-connected set in which each closed loop can be shrunk continuously to a point without leaving the set. Informally, the set is in one piece and has no hole that a loop can go around. On such domains, curl-free vector fields are conservative.

What this node needs for W2
  • edge instance_of in: at least two examples (0 of 2)
  • edge not_instance_of in: at least one non-example (0 of 1)
  • edge specializes both: the more general notions and the special cases (0 of 1)

The writing levels say how complete the text of a node is. They do not measure its truth.
