Resumen:
We study Fermi liquids with a Fermi surface that lacks continuous rotational invariance, and in the presence of an arbitrary quartic interaction. We obtain the expressions of the generalized static susceptibilities that measure the linear response of a generic order parameter to a perturbation of the Hamiltonian. We apply our formulae to the spin and charge susceptibilities.  Based on the resulting expressions, we make a proposal for the definition of the Landau parameters in non-isotropic Fermi liquid.
