%0 Journal Article %T The expected duration of random sequential adsorption %A Aidan Sudbury %J Mathematics %D 2008 %I arXiv %R 10.1214/07-AAP445 %X When gas molecules bind to a surface they may do so in such a way that the adsorption of one molecule inhibits the arrival of others. We consider random sequential adsorption in which the empty sites of a graph are irreversibly occupied in random order by a variety of types of ``particles.'' In a finite region the process terminates when no more particles can arrive. A universal asymptotic formula for the mean duration is given. %U http://arxiv.org/abs/0801.3184v1
