Title: The structure of free left distributive algebras under several relations
Abstract: A well-known result of Laver established that the closure of a single, non-trivial rank-to-rank (I3)
embedding under application forms a free left distributive algebra that is linearly ordered under iterated left
division. The linearity was then shown to be a ZFC result by Dehornoy. We survey existing results on the
structure of free left distributive algebras on one and many generators as well as the finite approximations
to the free left distributive algebras (Laver tables) and present some new results and open problems.
Included are some remarks about logical strength.

Title: Large cardinals need not be large in HOD
Abstract: I will show that large cardinals, such as measurable, strong and supercompact cardinals, need not exhibit their large cardinal nature in HOD. It is relatively consistent that a supercompact cardinal is not weakly compact in HOD, and one may construct models with a proper class of supercompact cardinals, none of them weakly compact in HOD. This is current joint work with Cheng Yong.
