摘要：
The process of relaxation to a suddenly created local potential is studied in (quasi-) two-dimensional metals with van Hove points near the Fermi surface. The new intermediate time-asymptotic for the core hole Green's function is found. It was found that the problem cannot be described in terms of creation of independent electron-hole pairs.
