Let integer n3 and integer r = r(n) 3. Define the binomial random r-uniform hypergraph H r (n, p) to be the r-uniform graph on the vertex set [n] such that each rset is an edge independently with probability p. A hypergraph is linear if every pair of hyperedges intersects in at most one vertex. We study the probability of linearity of random hypergraphs H r (n, p) via cluster expansion and give more precise asymptotics of the probability in question, improving the asymptotic probability of linearity obtained by McKay and Tian, in particular, when r = 3 and p = o(n −7/5 ).
