On the Hartogs–bochner Phenomenon for Cr Functions in P2(c)

Let M be a compact, connected, C2-smooth and globally minimal hypersurface M in P2(C) which divides the projective space into two connected parts U+ and U. We prove that there exists a side, U or U+, such that every continuous CR function on M extends holomorphically to this side. Our proof of this theorem is a simplification of a result originally due to F. Sarkis.

De l'oprateur de trace dans les jeux de Conway

In this report, we propose a game semantics model of intuitionistic linear logic with a notion of brackets and a trace operator. This model is a revised version of Conway games augmented with an algebraicly defined gain which enable to describe well bracketed strategies. We then show the existence of a free cocommutative comonoid in the category of Conway. To conclude, we propose a new model of...

Détection de contradiction dans les commentaires

Analysis of opinions (reviews) generated by users becomes increasingly exploited by a variety of applications. It allows to follow the evolution of the opinions or to carry out investigations on products. The detection of contradictory opinions about a Web resource (e.g., courses, movies, products, etc.) is an important task to evaluate the latter. In this paper, we focus on the problem of dete...
