DESCRIPTION:I will report on morphological estimators of the filamentary s
 tructure\nof the Cosmic Web\, the so-called skeleton.  Based on a global s
 tudy of\nthe matter density gradient flow\, it allows us to study the conn
 ectivity\nbetween a density peak and its surroundings\, with direct releva
 nce to\nthe anisotropic accretion via cold flows on galactic halos. It als
 o\nprovides a theoretical framework to study their cosmic evolution throug
 h\nthe onset of gravity-induced non-linearities.\nhttp://uk.arxiv.org/abs/
