Abstract: 

We study the ring Q-homeomorphisms with respect to p-modulus, p ˃ 2, in the complex plane and establish lower bounds for the area of an image of a disc. The extremal problem concerning a minimization of the area functional is solved.

Keywords: area functional, capacitor, p-capacitance of a capacitor, p-modulus of a family of curves, ring Q-homeomorphisms
