Let ak, k=1,2,3, be distinct points of the circle U={z:¦z¦3+k=1/¯ak, k=1,2,3. Let D1,...,D6 be a system of nonoverlapping simply connected domains D1,...,D6 on,ak?Dk, k=1,...,6. Let R(Dk,ak) be the conformal radius of the domain Dk with respect to the point ak. One formulates the following theorem. For any points ak?U, k=1,2,3, and any system of the indicated domains one has the sharp inequality One points out all the cases when equality prevails in (1). One indicates the main steps of the proof of this theorem.

Problem of the maximum of the product of the conformal radii of nonoverlapping domains in a circle
