Query: The Topology of The Cosmic Microwave Background Anisotropy on The Scale
  1 degree   In this paper we develop the theory of clusterization of peaks in a Gaussian
random field. We have obtained new mathematical results from this theory and
the theory of percolation and have proposed a topological method of analysis of
sky maps based on these results. We have simulated $10^o\times10^o$ sky maps of
the cosmic microwave background anisotropy expected from different cosmological
models with $0.5^o-1^o$ resolution in order to demonstrate how this method can
be used for detection of non-Gaussian noise in the maps and detection of the
Doppler-peak in the spectrum of perturbation of $\gD T/T$.
