Institute of Mathematics, Ukrainian National Academy of Sciences, Kiev, Ukraine

Abstract: We study metric properties of the ring $Q$-homeomorphisms with respect to the $p$-modulus, $p>2$, in the complex plane and establish lower bounds for the areas of disks. The extremal problem concerning minimization of the area functional is also solved.

Key words and phrases: ring $Q$-homeomorphism, $p$-modulus of families of curves, capacitor, $p$-capacitance of a capacitor, area functional.
