I spent pretty much the entirety of April 2012 writing an essay with the title Multiplicative Coalescence, as part of my Part III exams. As the results have now been published, this is probably an acceptable time to publish it here, in case anyone is interested. I certainly enjoyed writing the review, and hopefully some people may find it an interesting introduction to the more analytical side of the topic.
