Garside and quadratic normalisation: a survey
Starting from the seminal example of the greedy normal norm in braid monoids,
we analyse the mechanism of the normal form in a Garside monoid and explain how
it extends to the more general framework of Garside families. Extending the
viewpoint even more, we then consider general quadratic normalisation
procedures and characterise Garside normalisation among them.Comment: 30 page

Extragalactic line surveys
40 years have passed since the first molecular detection outside our Galaxy.
Since then, our knowledge on the distribution, kinematics and composition of
the molecular material in the extragalactic ISM has built up significantly
based not only on the carbon monoxide observations but also in the more than 50
molecular species detected. In particular, line surveys have been proven to be
excellent tools to study the chemical composition in the nuclei of galaxies.
Such studies have been favored by the increasing instantaneous bandwidth of
current mm and sub-mm facilities. Here I will summarize the highlights of
extragalactic molecular spectroscopy, mostly focusing in the results from
molecular line surveys published in the last few years as well as the aims of
still ongoing projects.Comment: 9 pages, 2 figures, in Proceedings of the 280th Symposium of the

Cosmic shear surveys
Gravitational weak shear produced by large-scale structures of the universe
induces a correlated ellipticity distribution of distant galaxies. The
amplitude and evolution with angular scale of the signal depend on cosmological
models and can be inverted in order to constrain the power spectrum and the
cosmological parameters. We present our recent analysis of 50 uncorrelated VLT
fields and the very first constrains on () and the nature of
primordial fluctuations based on the join analysis of present-day cosmic shear
surveys.Comment: Latex, 7 pages. To appear in the ESO Proceedings ``Deep Fields'',
