dc.description.abstract1Let G be a profinite group. The coprime commutators γ∗ j and δ∗ j are defined as follows. Every element of G is both a γ∗ 1 -value and a δ∗ 0 -value. For j ≥ 2, let X be the set of all elements of G that are powers of γ∗ j−1-values. An element a is a γ∗ j -value if there exist x ∈ X and g ∈ G such that a = [x, g] and (|x|, |g|) = 1. For j ≥ 1, let Y be the set of all elements of G that are powers of δ∗ j−1-values. The element a is a δ∗ j -value if there exist x, y ∈ Y such that a = [x, y] and (|x|, |y|) = 1. In this paper we establish the following results. A profinite group G is finite-by-pronilpotent if and only if there is k such that the set of γ∗ k-values in G has cardinality less than 2ℵ0 (Theorem 1.1). A profinite group G is finite-by-(prosoluble of Fitting height at most k) if and only if there is k such that the set of δ∗ k-values in G has cardinality less than 2ℵ0 (Theorem 1.2).pt_BR
