Abstract: In the study of 3-manifold topology, Heegaard splittings are a common and well researched approach. However, for many 3-manifolds, an alternative to the usual splitting is possible: a so-called one-sided Heegaard splitting. In comparison to their two-sided counterparts, one-sided splittings have been the basis of very little research. It is the study of the properties of these splittings, particularly in the light of recent developments in two-sided splitting theory, that forms the basis of my current PhD research.

The intention of this talk is to present the concept of one-sided splittings and discuss some of the specific areas that I am investigating. While some knowledge of 3-manifolds and two-sided Heegaard splittings would be useful, I will cover background material that relates directly to the topic.
