[Alta-Logic] Peripatetic Seminar Today

[Geoff Vooys]

Hi Everybody,

Today the Peripatetic Seminar will continue with a talk by Florian Schwarz at 14:00 in ICT 616! He'll tell us more things about bicategories and the way limits are extended to higher categorical frameworks. Talk details follow below, but in the meantime I hope to see you all there!

Cheers,
Geoff

Title: Bilimits in bicategories

Time: 14:00

Location: ICT 616

Abstract: Limits are central within category theory. If you pick a random concept within any area of mathematics, chances are it is a limit.
As part 5 of the series of bicategories, I will introduce the notion of a bilimit in a bicategory. For this we will have a look at the classical definition of limitis and reformulate it until we can attach a (bi-) to the right words and obtain the correct definition. This doesn't just give us a definition in bicategories, it also gives another structural perspective on limits in 1-categories. In the end we will look at a specific example of a bilimit in the bicategory of categories.
