Abstract

Graphs, also known as networks, are used to represent many kinds of relationships between pairs of entities. For example, a graph may describe pairs of networking devices directly connected together or pairs of roadway intersections connected by a stretch of road. Many useful tasks, such as understanding the reliability of a computer network or finding the fastest route between two locations, can be performed by doing computations on these graphs. When a graph has certain properties such as being drawable on a piece of paper without crossings between its connections, it becomes possible to do these types of computations much more quickly than if the properties were not present. Many of these faster computations rely on important results from topology, the mathematical study of what properties geometric objects maintain after certain types of deformations. This project seeks to better understand the role topology can take both in performing fast computations on graphs and explaining what graph properties are necessary for these fast computations. The project aims to make substantial topology based additions to the toolkit used in graph computations. These additions should make new computational tasks possible and greatly simplify established tasks. The project involves a substantial education component as well that includes educating students on the known connections between topology and computer science and providing undergraduate minority students their first opportunities t
