Query: Complex-valued second difference as a measure of stabilization of
  complex dissipative statistical systems: Girko ensemble   A quantum statistical system with energy dissipation is studied. Its
statistics is governed by random complex-valued non-Hermitean Hamiltonians
belonging to complex Ginibre ensemble. The eigenenergies are shown to form
stable structure. Analogy of Wigner and Dyson with system of electrical charges
is drawn.
