We consider the last passage percolation (LPP) model on the square lattice with symmetric weights. Tuning the weights on the diagonal, and letting the endpoint move away from the diagonal, we obtain a crossover between the Tracy-Widom GUE, GOE and GSE distributions from random matrix theory. The LPP time can be seen as a marginal of a certain point process - the Schur process with a free boundary - and we shall explain this connection and how it can be used to obtain our results. Joint work with Jérémie Bouttier, Dan Betea and Mirjana Vuletic.

After recalling the basic notions coming from differential geometry, the colloquium will be focused on spaces satisfying Ricci curvature lower bounds.
The idea of compactifying the space of Riemannian manifolds satisfying Ricci curvature lower bounds goes back to Gromov in the ‘80s and was pushed by Cheeger and Colding in the ‘90s who investigated the fine structure of possibly non-smooth limit spaces. A completely new approach via optimal transportation was proposed by Lott-Villani and Sturm almost ten years ago. Via such an approach one can give a precise definition of what means for a non-smooth space to have Ricci curvature bounded below. Such an approach has been refined in the last years giving new insights to the theory and yielding applications which seems to be new even for smooth Riemannian manifolds.

Dr Kathy Ehrensperger: Become fellowimitators together with me (Phil 3.17): Embodying Christ in the Face of the “Enemies of the Cross

The first half of this talk is on principles of functional programming in Mathematica, in which we will discuss the use of options and attributes, the development of custom notations, and how functional programming fits into the practice of physics. The second half will discuss techniques for organising computations, including namespaces and scoping, debugging techniques, package-generation by notebooks, and the implementation of multiple systems of backups.
