Abstract

Given α > 0 and an integer 5, we prove that every sufficiently large 3-uniform hypergraph H on n vertices in which every two vertices are contained in at least αn edges contains a copy of C, a tight cycle on  vertices minus one edge. This improves a previous result by Balogh, Clemen, and Lidický.
