Model Theory - part 04 - Posets, Lattices, Heyting Algebras, Booleans Algebras
This is a short video for people who haven't seen a Heyting algebras before. There is really nothing special in it that doesn't show up in wikipedia or ncatlab. I just wanted to review it before we use them. Errata: *at 3:35: there the law should read (a and (a or b) ), not (a and (a and

Albert Visser: The absorption law for slow provability
The lecture was held within the framework of the Hausdorff Trimester Program: Types, Sets and Constructions. Abstract: The absorption law for slow provability states that, if it is provable that A is slowly provable, then A is provable. We give a simple proof of the absorption law for a v

Francesco Ciraulo: Notions of Booleanization in pointfree Topology
The lecture was held within the framework of the Hausdorff Trimester Program: Types, Sets and Constructions. Abstract: Boolean algebras play a key role in the foundations of classical mathematics. And a similar role is played by Heyting algebras for constructive mathematics. But this is
