Commensurability of some capacitieswith harmonic capacities M. Ya.Mazalov For x = (x 1 , . . ., x N ) ∈ R N , N ⩾ 3, let р L(x) be a second-degree homogeneous polynomial in R N with constant complex coefficients which satisfies the condition of ellipticity L(x) = 0 ⇔ x = 0.The following result was established in [1], Lemma 3.
