Title: A two-scale method for the Integral Fractional Laplace equation and the Fractional Obstacle problem

Abstract: In this talk, we are interested in the approximation of integral Fractional Laplace equation. The continuous problem satisfies a maximum principle, which is essential for the analysis of the Fractional Obstacle problem. Motivated by this application, we propose a two-scale method for the linear problem, which inherits the maximum principle naturally and leads to L-estimates for the error. We present the discretization of the Fractional Obstacle Problem as a possible application of the method and its error analysis. The work presented is in collaboration with R.H. Nochetto, J.P. Borthagaray and A. Salgado.

Title: The Theory of Nonlocal Games and the problems of Tsirelson and Connes

Abstract: In Lecture 2, we focus on synchronous quantum correlations and their relationship with traces on algebras. We derive a set of fundamental orthogonality relations that must be satisfied by an algebra to yield a perfect strategy and show how these results lead to a stronger refutation of Connes Embedding Problem.
