Hyperbolic Eisenstein series for geometrically finite hyperbolic   surfaces of infinite volume
  For a geometrically finite hyperbolic surface of infinite volume we write down the spectral decomposition for the Laplacian on 1-forms, generalize the Kudla and Millson's construction of hyperbolic Eisenstein series and other related results.
