Summary
Random methods have become one of the most active and fruitful areas of research in many areas of mathematics, science and engineering, most notably in combinatorics and computer science, in an interplay with probability theory. These series of courses will cover a wide spectrum of these interactions, including random graphs, random trees, extremal combinatorics and random geometric graphs.
Schedule
22nd May 2017 to 16th June 2017
- Week 1: 22nd May to 26th (5 hours)
- Week 2: 29th May to 2nd June (5 hours)
- Week 4: June 12th to 16th (10 hours)

Title: Random Strategies are Nearly Optimal for Generalized van der Waerden Games.
Abstract: We study the biased version of a strong generalization of the van der Waerden games introduced by Beck as well as the hypergraph generalization of the biased H-games previously studied by Bednarska and Luczak. In particular,we determine the threshold biases of these games up to constant factors by proving general winning criteria for Maker and Breaker based on their ideas. As in the result of Bednarska and Luczak,the random strategy for Maker is again the best known strategy.

Programa
12.30 Francisco Presas (ICMAT-CSIC)
Symplectic topology and Hamiltonian dynamics: a love story.
Historically, symplectic geometry appeared as a geometric setup for Hamiltonian dynamics. The Hamiltonian side influenced the geometric aspects at the beginning of the story. In the eighties, however, the discovery of rigidity phenomena in Symplectic Geometry turned around the table. We want to describe in this talk the conjectures, nurtured by Symplectic rigidity, that have grown up in the last thirty years. Most of them have to do with the existence/non-existence of periodic orbits in general Hamiltonian systems. Finally, we would address some more recent results addressing the existence of minimal flows in Hamiltonian dynamics.

On Linear Point Billiards
Motivated by the high-energy limit of the N-body problem we construct a non-deterministic billiard process, whose table is the complement of afinite collection of linear subspaces within a Euclidean vector space. A trajectory is a constant speed, piecewise linear curve with vertices on the subspaces and changes of directions upon hitting a subspace constrained by `conservation of momentum' (mirror reflection). The itinerary of a trajectory is the sequence of subspaces it hits. We will describe a fundamental theorem of Burago-Ferleger-Kononenko on the finiteness of itineraries, and a description of the space of trajectories having a fixed itinerary, which has emerged recently in a joint work with Andreas Knauf and Richard Montgomery, as a Lagrangian relation on the space of lines in the Euclidean space. Our method combines those of BFK in non-smooth metric geometry, with generating families.
