Graduate Logic Seminar
The Graduate Logic Seminar is an informal space where graduate student and professors present topics related to logic which are not necessarly original or completed work. This is a space focused principally on practicing presentation skills or learning materials that are not usually presented in a class.
- When: Mondays 4p-5p
- Where: TBD.
- Organizers: Omer Mermelstein
The talk schedule is arranged at the beginning of each semester. If you would like to participate, please contact one of the organizers.

Title: Lattice Embeddings of the m-Degrees and Second Order Arithmetic
Abstract: Lachlan, in a result later refined and clarified by Odifreddi, proved in 1970 that initial segments of the m-degrees can be embedded as an upper semilattice formed as the limit of finite distributive lattices. This allows us to show that the many-one degrees codes satisfiability in second-order arithmetic, due to a later result of Nerode and Shore. We will take a journey through Lachlan's rather complicated construction which sheds a great deal of light on the order-theoretic properties of many-one reducibility.
