Abstract
We derive the Caldeira-Leggett-type action describing electron tunneling th rough a quantum point contact between two compressible Quantum Hall liquids for both diffusive and ballistic regimes of the bulk electron motion. Alth ough the edges of the system can not be identified as a Luttinger liquid of any kind, the current-voltage characteristic demonstrates only small, yet systematic, deviations from a pure power-law I similar to V-1/nu.
