Parmi les travaux cruciaux dans la theorie des representations, il y a ceux qui etudient la construction explicite de certaines representations de niveau un des algebres de kac-moody affines, en termes d'algebres d'operateurs vertex. Rappelons que le niveau d'une representation est l'action du centre de cette algebre. Il est difficile de construire les representations de niveau plus grand que un. C'est pour cela que les specialistes se sont interesses a la conjecture suivante qui est connue depuis une dizaine d'annees: toute representation irreductible de plus haut poids dominant et de niveau

The development of novel technologies is allowing a complete description of the heart structure and function, including geometrical, myocardial tissue viability and electrical activation information. The joint analysis of this information helps to improve clinical interventions such as radio-frequency ablation of cardiac arrhythmias. However, the acquired data and related indices need to be integrated onto a common reference space for its analysis. This integration is not straightforward due to the different characteristics of acquisition systems. The aim of this thesis was to develop and eva

Abstract:
Artificial Intelligence Planning is about acting in order to achieve a desired goal. Under incomplete information, the task of finding the actions needed to achieve the goal can be modelled as a search problem in the belief space. This task is costly, as belief space is exponential in the number of states, which is exponential in the number of variables. Good belief representations and heuristics are thus critical for scaling up in this setting. The translation-based approach to automated planning with incomplete information deals with both issues by casting the problem of search in beli

We show that any positive energy representation of the group of (orientation preserving) smooth diffeomorphisms of the circle Diff(S^1) can be extended to a strongly continuous unitary projective representation of the group of (orientation preserving) fractional Sobolev diffeomorphisms D^s(S^1) with real Sobolev exponent s>3. For some positive energy representations, i.e for the positive energy vacuum representations of Diff(S^1) with positive integer central charge, we can improve the implementation to the group D^s(S^1) with s>2.

Abstract:
When dealing with Quantum Information objects in Quantum Field Theory (QFT), the algebraic approach seems a good choice, since the tools regarding quantum entropy can be formulated very precisely in terms of operator algebras. Quantum information aspects of QFT naturally take place in the framework of quantum black holes thermodynamics, as for example the Bekenstein Bound and the Landauer's principle show. However, more unexpected and interesting connections between the relative entropy and the stress energy tensor have arisen, and in particular it is of interest to provide and prove an axioma
