“Series parallel posets and NU polymorphisms”
In this talk I will try to explain what series parallel posets are and how to find 5-ary NU polymorphism on them.

"Hopf Modules and Integrals"
Let $H$ be a hopf algebra. We will prove the fundamental theorem of $H$ hopf modules. After that we investigate the connection between integrals and the rational part of $H^*$.

"Logical unification"
I will talk on preliminary work on the role of [0,1]-valued
logic in unifying the growing number of first order logics. In
particular, elementary classes in [0,1]-valued logic are CATs in the
sense of Ben Yaacov and the class of von Neumann algebras with faithful
actions on Hilbert spaces form an elementary class.

"The Dinitz Problem and Five-Colouring Plane Graphs"
G. H. Hardy firmly believed that there is no permanent place for ugly Mathematics. Following his dictum, Paul Erdos liked to talk about "The Book" in which God maintains the perfect proofs for mathematical theorems. This talk is an attempt to explore Erdos' idea of perfect proofs, and the territory we choose to explore is graph theory.

We finish off chapter 6 of Goldblatt: we discuss logical semantics in the context of an arbitrary topos. We then begin chapter 5: we see some first categorical properties of topoi.

"Four Dimensional Polytopes of Minimum Positive Semidefinite Rank"
For a given polytope the smallest size of a semidefinite extended
formulation can be bounded from below by the dimension of the polytope
plus one. This talk is about polytopes for which this bound is tight,
i.e. polytopes with positive semidefinite (psd) rank equal to their
dimension plus one.
