Ultrafilters and ultraproducts
Leeds Pure Mathematics Postgraduate Seminar, 12th February 2015
Abstract:
I will give an introductory talk to the fun world of ultrafilters and ultraproducts, covering basic definitions, results and examples. I will do my best to make the talk accessible, although I should warn non-logicians that the section on ultraproducts may be difficult to follow without knowledge of first-order logic.
