Abstract

We show that for d≥ d0(ε), with high probability, the random graph G(n,d/n) contains an induced path of length (3/2-ε)(n)/(d)log d. This improves a result obtained independently by Luczak and Suen in the early 90s, and answers a question of Fernandez de la Vega. Along the way, we generalize a recent result of Cooley, Draganić, Kang and Sudakov who studied the analogous problem for induced matchings.
