## Non-orientable 4-manifolds

##### Abstract:

I will talk about why some classical theorems (e.g. Waldhausen, Laudenbach-Poenaru) can be modified to hold for non-orientable 3- and 4-manifolds. As a consequence, we can draw Kirby diagrams and trisection diagrams and conclude the usual main trisection theorems for non-orientable 4-manifolds. This is joint work with Patrick Naylor (University of Waterloo).
