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).
