Описание:
Basic properties of plane graphs (from 28:40).
Plane vs planar: are maximally plane graphs maximally planar?
(Proof of Lemma 4.2.8 omitted; assume Lemma 4.2.6 for a simpler proof.)
Surfaces and their classification (35:15). Euler characteristic: an invariant of surfaces.
Proof of Euler's formula for graphs (from 44:47).
Example of double counting (1:05:30).
Covers rest of Chapter 4.2.
Based on R.Diestel, Graph Theory, Springer GTM173, 6th edition 2025.
