Abstract

We show that for sufficiently large n, every 3-uniform hypergraph on n vertices with minimum vertex degree at least (n-12)-(34n-2)+c, where c=. 2 if n∈4N and c=. 1 if n∈2N-4N, contains a loose Hamilton cycle. This degree condition is best possible and improves on the work of Buß, Hàn and Schacht who proved the corresponding asymptotical result.
