[112.02] Peculiarities of the Topology of the CMB Polarization field

D. Novikov (Univ.of Kansas), P. Naselsky (Rostov State Univ.)

We study the statistical properties of the Cosmic Microwave Background polarization field. We pay the special attention to the following two features of the 'strongly' and 'weakly' polarized spots: first, the classification and statistics of the singular points of the polarization field where polarization is equal to zero; second, the topology of contours of the value of the modulus of polarization with special emphasis on the percolation properties for the zones of 'strong' and 'weak' polarization.
