The special case in which the in-degrees are obtained by conditioning independent random variables with a specially chosen negative binomial distribution on their sum corresponds in distribution to a process for choosing random mappings which exhibits preferential attachment - images are chosen one at a time, and vertices chosen as images earlier in the process are more likely to be chosen again. They consider the functional digraph as a random object, and study its properties.We generalize Hansen and Jaworski’s preferential attachment model to a new setting: our model produces digraphs with labeled arcs and uniform out-degree k; other than a few technical wrinkles, the graph obtained by ignoring arc directions, loops, and multiple arcs is essentially a preferential attachment version of the k-out graph model first studied by Fenner and Frieze. This dissertation splits nicely in to three parts: first, we build a collection of analytical tools for studying our mapping; second, we study structural properties of its induced graph, including minimum vertex degree, vertex connectivity, and the k-core; finally, we present a very strong measurement of the differences and similarities between our model and a limiting case that is uniformly random. 2013-08-28 English text The Ohio State University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=osu1370527839 http://rave.ohiolink.edu/etdc/view?acc_num=osu1370527839 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
