Pointfree theories of T0 spaces

2024-09-24

Speaker: Anna Laura Suarez (CMUC, Univ. Coimbra)

Pointfree topology regards certain order-theoretical structures, called frames, as topological spaces. We regard frames as spaces in virtue of the lattice of open set of every space being a frame. Not all frames are lattices of open sets; nonetheless, studying all frames as spaces offers...

Some recent results on algebras of partial functions

2024-09-24

Speaker: Brett McLean (Ghent Univ., Belgium)

We will investigate algebraic structures that are isomorphic to a set of partial functions equipped with selected operations (e.g. composition, intersection, etc.). I will spend most of the time describing results about completely representable algebras - these are the algebras that can be...
