"Embedding Lattices into the Computably Enumerable Degrees"
The question of which finite lattices can be embedded into the c.e.
degrees first arose with the construction of a minimal pair by Yates,
and independently by Lachlan, showing the 4 element Boolean algebra
can be embedded. This result was rapidly generalised to show any
finite distributive lattice can also be embedded. For non-distributive
lattices, the situation is more complicated.

"An Introduction to Boole's Algebra of Logic for Classes"
Boole's mysterious algebra of logic, based on the algebra of numbers and idempotent variables, has only been properly understood and justified in the last 40 years, more than a century after Boole published his most famous work, Laws of Thought. In this talk an elementary and natural development of Boole's system, from his partial algebra models up to his four main theorems, will be presented.
