Colloquium in Mathematics and Computer Science,
New applications of the circular symmetrization to the multivalent functions

Earlier we proposed a new version of the circular symmetrization of the condensers on the Riemann surfaces [1]. This transformation of condensers allows to obtain new results taking into account the ramification points of the surfaces (for more details, see [2]). In the present talk, we discuss the applications of the symmetrization to p-valent functions, circumferentially mean p-valent functions and complex polynomials [3]-[6].
