Menger compacta, where logic meets homotopy

Aristotelis Panagiotopoulos (UIUC)

Abstract: Category theory emerged from -and resulted in- the shift of focus from the study of one object in isolation to the study of the relations between many objects of the same sort. In this talk, we will explain how we can often reduce the study of a category back to the study of a unique object in isolation. This object is known as the Fraisse limit of the category. We will illustrate this using examples from model theory and topology.
