Is my induction proof of the handshake lemma correct?

WebAug 6, 2013 · I Googled "graph theory proofs", hoping to get better at doing graph theory proofs, and saw this question. Here was the answer I came up with: Suppose G has m connected components. A vertex in any of those components has at least n/2 neighbors. Each component, therefore, needs at least (n/2 + 1) vertices. WebMay 21, 2024 · To prove this, we represent people as nodes on a graph, and a handshake as a line connecting them. Now, we start off with no handshakes.
