Resumen:
We introduce a path-integral approach that allows to compute charge density
oscillations in a Luttinger liquid with impurities. We obtain an explicit expression
for the envelope of Friedel oscillations in the presence of arbitrary
electron-electron potentials. As examples, in order to illustrate the procedure, we
show how to use our formula for contact and Coulomb potentials.
