DESCRIPTION:The morphology of galaxies is set by their angular momentum di
 stribution. In turn\,  filaments of the cosmic web drive the angular momen
 tum acquisition of galaxies. The anisotropic environment  set by the web c
 an be used to revisit  tidal torque theory near its saddle points. The cor
 responding constrained mis-alignment between the tidal tensor and the hess
 ian of the density field simply  explains  the point-symmetric geometry of
  the angular momentum distribution  within filaments. This Lagrangian theo
 ry allows us to relate the transition mass corresponding to  the alignment
  of dark matter halos' spin to this  geometry\, and to predict accordingly
  its  scaling with the mass of non linearity.
