WebThe discrete version of Cheeger’s inequality was considered in [17, 3] with proof techniques quite similar to those used for the continuous case by Cheeger [5], and can be traced back to the early work of Polya and Szego [21]. The implications of the above isoperimetric inequalities can be summarized WebThe Cheeger’s inequality shows that the converse of the above also holds with a quadratic loss. Theorem 17.1 (Discrete Cheeger’s inequality). For any graph G, 2=2 ˚(G) p 2 2: In …
