Query: Constraints on the neutrino mass and the cosmological constant from
  large scale structure observations   The observational data on the large scale structure (LSS) of the Universe are
used to establish the upper limit on the neutrino content marginalized over all
other cosmological parameters within the class of adiabatic inflationary
models. It is shown that the upper 2$\sigma$ limit on the neutrino content can
be expressed in the form $\Omega_{\nu}h^2/N_{\nu}^{0.64}\le0.042$ or, via the
neutrino mass, $m_{\nu}\le4.0$eV.
