Algebra & logic seminar (JGH 219, F 9-10, M. Greer)

May 10, 17: Riquelmi Cardona Fuentes, TBA

May 3: Nick Galatos, The finite embeddability property for integral residuated lattices

Abstract: Riquelmi will be presenting some of his recent results in the next two weeks. This Friday I will give some of the background material and some relevant results in the literature. The finite embeddability property (FEP), a strong property that implies decidability of equations and more, fails for the whole variety of residuated lattices. I will be assuming integrality of the algebras and show that the FEP holds then (integral cases include Boolean algebras and Heyting algebras). Under assumptions weaker than integrality, known as knotted rules, the FEP still fails, but the property is recovered if we further assume commutativity. Riquelmi will be pushing the envelope by relaxing the commutativity assumption to other semigroup identities. Some of the theory of well-ordered sets comes into the game and is used to ensure finiteness.

Analysis & dynamics seminar (JGH 219, Fr 10-11, R. Pavlov)

May 17: Florian Sobieczky, Amenable graphs of exponential growth

Abstract: Using techniques such as `thermodynamic limits' for functionals on graphs requires the ability to neglect the influence of so called finite-size effects. Therefore, amenable graphs, for which there is a `Foelner-sequence' are prominent candidates for the application of such techniques. Now, homogeneous infinite trees, however, are non-amenable, as is the overwhelming majority of exponentially growing graphs. In this talk, we investigate criteria of amenability for so called horocyclic products of trees. These are applicable to random trees (such as Galton-Watson trees), as well as uniformly growing trees. They are closely linked to the so called Lamplighter-group. The result suggests a method to embed any non-amenable graph of finite geometry into an amenable one.
