I will discuss the homological structure of the classifying space of 2d-dimensional (d-1)-connected manifolds. This generalizes the case of surfaces where the stable homology was predicted by the Mumford conjecture and the actual homology by the Harer stability theorem. The methods involve rational homotopy theory and surgery theory.

In our data-rich world, key medical decisions, ranging from a regulator's decision to curtail a drug to patient-specific treatment choices, require optimal consideration of myriad inputs. Statistical/epidemiological methods that can harness real-world medical data in useful ways do exist, but much work remains to achieve the full potential of a ...

The counterfactual approach to casual inference dates back at least to Neyman and has developed considerably in recent decades due to pioneering work by Rubin, Pearl, Robbins, and others. This lecture will introduce the counterfactual approach and discuss specific examples.

Graphical Markov models use graphs with nodes corresponding to random variables, and edges that encode conditional independence relationships between those variables. Directed graphical models (aka Bayesian networks) in particular have received considerable attention. This lecture will review basic concepts in graphical model theory such as Mark...

Joint work with Julien Salomon.In this presentation we present and illustrate a greedy algorithmthat enables in a first stage to design a set of selective laser fields that can in a second stage be used to identify some unknown parameters of quantum systems for a problem ofHamiltonian Identification.

Approximation of non linear eigenvalue problems represent the key ingredient in quantum chemistry. These approximation are much computer demanding and these approximations saturate the ressources of many HPC centers. Being nonlinear, the approximation methods are iterative and a way to reduce the cost is to use different grids as has been propos...

Theoretically equilibrium possibilities may be expanded by reducing the number of critical states. Furthermore, nonlinear valuation procedures may be used to assist the attainment of an expanded equilibrium with fewer securities than even the number of critical states. Practically, risk is an exposure to change in value or the variation in value...

This talk will be about a novel technique called 'spatial coupling' originally invented for constructing better error correcting codes. One can use spatial coupling as a mathematical tool to derive properties of 'standard' graphical models via an analysis of a 'coupled version'. A general methodology for obtaining provable better (sometimes opti...
