Using Ryja c ek's closure, we prove that any 3-connected claw-free graph of order & and minimum degree $ &+38 10 is hamiltonian. This improves a theorem of Kuipers and Veldman who got the same result with the stronger hypotheses $ &+29 8 and & sufficiently large and nearly proves their conjecture sa
## Abstract Let __cl__(__G__) denote RyjΓ‘Δek's closure of a clawβfree graph __G__. In this article, we prove the following result. Let __G__ be a 4βconnected clawβfree graph. Assume that __G__[__N__~__G__~(__T__)] is cyclically 3βconnected if __T__ is a maximal __K__~3~ in __G__ which is also maxim
