Query: Longitudinal electric conductivity and dielectric permeability in
  quantum plasma with constant collision frequency in Mermin' approach   Detailed deducing of formulas for longitudinal electric conductivity and
dielectric permeability in the quantum degenerate collisional plasma with
constant collision frequency in Mermin' approach is given. The kinetic
Schr\"{o}dinger-Boltzmann equation in momentum space in relaxation
approximation is used. It is shown that when collision frequency of plasma
particles tends to zero (plasma passes to collisionless one), the deduced
formula for dielectric function passes to the known Lindhard' formula for
collisionless plasmas. It is shown that the deduced formula for dielectric
permeability coincides with known Mermin's formula. Graphic research of the
real and imaginary parts of dielectric function is made. Graphic comparison of
the real and imaginary parts of dielectric function for quantum and classical
plasma also is made. The module of derivative dielectric function also has been
investigated graphically.
