Our first seminar of the winter term will be this Wednesday, January 27th,
2:30-3:30:
Double Categories and the Monoids and Modules Construction
Double categories are a useful tool to organize structures which have two
different types of maps between the same objects, but which are related in
that the "maps-between-maps" are similar. We will discuss a certain kind
of double category, and look at a number of examples. We will then
describe the remarkable "monoids and modules" construction, which builds
complicated double categories out of simpler ones.
