Operator representation of the Dirac Coulomb Green function and relativistic polarizability of hydrogen-like atoms

The Dirac Coulomb Green function in the representation of the annihilation and creation operators is established and on the basis of the application of this new operator representation an algebraic method of calculation of atomic characteristics is briefly discussed. The relativistic polarizability of hydrogen-like atoms is calculated and its simple analytical formula is obtained.
