Abstract In an ongoing collaboration with Pierre Germain and Tristan Léger, we are interested in the L2 - Lp norms of spectral projectors in small spectral windows on hyperbolic surfaces of infinite area. In the absence of "  cusps ", we obtain …

Abstract Using PSL(2, R) representation theory, we study the temporal correlations of two observables propagated by the geodesic flow of a hyperbolic surface. If the observables are sufficiently regular, these correlations can be developed asymptotically …

Abstract The oral modality is the most natural channel for linguistic interaction, but current language technologies (NLP) are mainly based on the written word, requiring large quantities of text to develop language models. Even voice assistants or speech …

Abstract From " postcolonial " criticism to " decolonial " thinking Faced with " multiversity ", the challenge of open universalism The spectre of …

Abstract Language models, a research direction independent of vector representation during the pre-neuronal era. Their recent evolution and encounter, up to neural contextual language models. Recurrent architectures (including LSTMs) and Transformer …

Abstract Most stars have a magnetic field. If the star is cold, this magnetic field is dynamo, i.e. continuously generated by the star itself. If the star is hot, the field is of fossil origin, i.e. a relic of the star's formation. The presence of a …

Abstract Modernity does not have a monopoly on universalism. The term itself dates from the 19th  century. On the other hand, the claim to universality (the idea that certain ideas, or certain practices, are universal in scope, that their validity, …

Abstract Since 1914, astronomers have been classifying the wide variety of stars in the sky on the HR (Hertzsprung-Russell) diagram according to their surface temperature and luminosity. Stars spend most of their lives on the main sequence, fusing …

Abstract This final part of the lecture on the relationship between Osiris and the living is devoted to the role of the god as a recourse in legal proceedings. As early as the Old Kingdom, the " tribunal of the great god " was invoked as a place of …

Abstract In this talk we will discuss the asymptotic behavior of determinants of Laplacians on random surfaces of large genus. We will motivate this problem by questions related to quantum field theory and topology of hyperbolic manifolds. Documents and …

Abstract Transducers are a valuable tool in several distinct areas of linguistics. In morphology, they can be used to produce explicit and consistent descriptions of morphological paradigms, both for well-endowed languages and for languages with an oral …

Abstract Using PSL(2, R) representation theory, we study the temporal correlations of two observables propagated by the geodesic flow of a hyperbolic surface. If the observables are sufficiently regular, these correlations can be developed asymptotically …

Abstract The Keller-Segel equation describes the movement of cells by chemotaxis. Cells diffuse in the plane, and emit a chemical. This product, which also diffuses, attracts the cells. This leads to a singular interaction between the cells (via the …
