Fixing a complete first order theory T, countable for transparency, we had known quite well for which cardinals T has a saturated model. This depends on T of course - mainly of

whether it is stable/super-stable. But the older, precursor notion of having

a universal notion lead us to more complicated answer, quite partial so far, e.g

the strict order property and even SOP_4 lead to having "few cardinals"

(a case of GCH almost holds near the cardinal). Note that eg GCH gives a complete

We discuss joint work with Douglas Arnold, Guy David, Marcel Filoche and Svitlana Mayboroda.

Consider for the operator $L = -\Delta + V$ with periodic boundary conditions, and more

generally on the manifold with or without boundary. Anderson localization, a significant feature

of semiconductor physics, says that the eigenfunctions of $L$ are exponentially localized with

high probability for many classes of random potentials $V$. Filoche and Mayboroda introduced the

Classical group representation theory deals with group actions on linear spaces; we consider group actions on compact convex spaces, preserving topological and convex structure. We focus on irreducible actions, and show that for a large class of groups - including connected Lie groups - these can be determined. There is a close connection between this and the theory of bounded harmonic functions on symmetric spaces and their boundary values.

Title: The (in)compatibility of 3 and 5 dimensional Heisenberg geometry with Lebesgue spaces

Abstract: The 3-dimensional (discrete) Heisenberg geometry is the shortest-path metric on the infinite graph whose vertex set is the integer grid $\Z^3$ and the neighbors of each integer vector $(a,b,c)$ are the four integer vectors $$(a+ 1,b,c), (a- 1,b,c), (a,b+ 1,c+ a), (a,b- 1,c- a).$$

1) Abstract of Wayne's part:
Today, in our modern world, we perceive the physical universe in mathematical terms; whether degrees on longitude and latitude on earth, or in units of space-time beyond our earthly horizons. This talk will present two ancient cuneiform tablets from Babylonia which offer a geometric impression of the physical world as experienced by ancient Babylonians. Comparisons will be made with a range of other ancient mathematical, geographic, and astronomical materials from the cuneiform Ancient Near East.

A Hausdorff topological group G is said minimal if G does not admit any strictly coarser Hausdorff group topology.

Examples include the isometry group of the Urysohn sphere, due to Uspenskij, and Aut(M) for M stable and w-categorical, a deep fact due to Ben Yacov and Tsankov.
