Abstract

A well-known result of Burr, Erd\H{o}s and Spencer [Transactions of the American Mathematical Society, 1975] determines the 22-colour Ramsey number for any sufficiently large collection of vertex-disjoint copies of a fixed graph HH without isolated vertices. In this short note we prove a random version of this result, thereby generalising the random Ramsey theorem of R\"odl and Ruci\'nski [Journal of the American Mathematical Society, 1995].
