Title
Progress on the Murty-Simon Conjecture on diameter-2 critical graphs: a survey.
Abstract
A graph $$G$$G is diameter $$2$$2-critical if its diameter is two and the deletion of any edge increases the diameter. Murty and Simon conjectured that the number of edges in a diameter-$$2$$2-critical graph $$G$$G of order $$n$$n is at most $$\\lfloor n^2/4 \\rfloor $$¿n2/4¿ and that the extremal graphs are the complete bipartite graphs $$K_{{\\lfloor n/2 \\rfloor },{\\lceil n/2 \\rceil }}$$K¿n/2¿,¿n/2¿. We survey the progress made to date on this conjecture, concentrating mainly on recent results developed from associating the conjecture to an equivalent one involving total domination.
