Undue weight

It seems that undue weight is being given to "Murty's survey paper" in this article. While a survey paper might be useful for background, I fail to see why it would be considered notable. At best, maybe footnotable. 70.247.162.84 (talk) 22:50, 18 August 2012 (UTC)[reply]

λ(G) definition is suspect

Perhaps it should be $\lambda (G):=max_{i>0}|\lambda _{i}|$ , like in the expander graph article. — Preceding unsigned comment added by 178.38.179.63 (talk) 12:18, 11 December 2014 (UTC)[reply]
