| Abstract： | We give rigidity results for discrete Bonnet-Myers diameter boundand Lichnerowicz eigenvalue estimate. Both inequalities are sharp ifand only if the underlying graph is a hypercube. The proofs usewell-known semigoup methods as well as new direct methods whichtranslate curvature to combinatorial properties. The results can beseen as first known discrete analogues of Cheng'sand Obata's rigidity theorems. |
