Abstract The Milky Way's massive black hole is called Sagittarius A* and weighs 4 million times the mass of the Sun. Most galaxies have their own massive black hole, with a mass ~ 1 000 times smaller than the mass of the galaxy. We believe that these …

Abstract Every galaxy has a super-massive black hole at its center, whose mass is proportional to the mass of the central bulge or spheroid of stars. Black holes accumulate mass over time through accretion of gas from their disk, or through mergers …

Abstract Since 2014, the Centre Jean-Bérard has been engaged, together with the Archaeological Superintendency of Foggia and the University of Salerno, in a research program on one of the largest settlements in northern Apulia, " Arpi : forms and …

Abstract Fractal uncertainty principle states that if a function is Fourier localized to a fractal set, then only a very small part of its mass can live on another fractal set. In this talk I will state the fractal uncertainty principle and discuss two …

Abstract The lecture discusses phase transitions in a non-equilibrium fluid mixture following a model proposed by M. Cates and co-workers. It shows how Ostwald ripening can be reversed and lead to finite-size drop phases. References "On the Theory of …

Abstract When the format or mode of acquisition of an item of information is such that it can only concern the subject itself, it is not necessary to identify the person whom the information concerns as ourselves. The identification in question is …

Abstract " Le Garage hermétique de Jerry Cornélius ", developed as a serial for Métal hurlant magazine in the second half of the 1970s, then published as an album under the title " Major fatal ", remains Moebius's most fascinating work, a graphic novel …

At a time when most artists were losing interest in the tradition of drawing, comics helped to keep it alive. But for a long time, totally spontaneous drawing seemed almost forbidden, due to the constraints imposed by reproduction techniques. This is one …

Don Quixote in several episodes, with brief commentaries (French subtitles). The seminar is integrated with the lecture, and both are taught in a single session. Watch the video of the seminar and …

Don Quixote in several episodes, with brief commentaries (French subtitles). Discourses on identity, whether sexual, religious, ethnic or racial, are systematically marked by fear of otherness, disguised as phobia. The issue of integration is the struggle …

Abstract In this talk, we present some new rigidity results for minimal graphs on unbounded Euclidean domains. In particular, we prove that a positive minimal graph on a half-space, and under the homogeneous Dirichlet boundary condition, must be an affine …
