On the bipartite graph packing problem

The graph packing problem is a well-known area in graph theory. We consider a bipartite version and give almost tight conditions on the packability of two bipartite sequences

Trees and graph packing

In this thesis we investigate two main topics, namely, suffix trees and graph packing problems. In Chapter 2, we present the suffix trees. The main result of this chapter is a lower bound on the size of simple suffix trees. In the rest of the thesis we deal with packing problems. In Chapter 3 we give almost tight conditions on a bipartite packing problem. In Chapter 4 we consider an embedding problem regarding degree sequences. In Chapter 5 we show the existence of bounded degree bipartite graphs with a small separator and large bandwidth and we prove that under certain conditions these graphs can be embedded into graphs with minimum degree slightly over n/2
