Renormalized diagram expansions in effective parameter for charged model of water

Diagram series with respect to the electrostatic part of the interaction are constructed for the charged models widely used in the numerical modeling of polar systems. A renormalization procedure consisting of transition to irreducible diagrams is proposed. As a result of this transition, expansions with respect to an effective small parameter arise. The constructed expansion is used to solve the problem of the surface polarization at the water–vapor interface.
