AB - УДК 517.54We consider the known problem of geometric function theory on extremal partition of the complex plane. For this problem, we obtain estimates for the maximum value of the product of inner radii of $n$ disjoint domains with respect to $n$ arbitrary points in the complex plane. The exact solutions to this problem are currently known only for $n = 2,3,4.$ In this paper, we found estimates that can be applied to various extremal geometric problems of the theory of functions.
