Abstract The set 𝒦(θ) of all composite materials obtained by mixing two isotropic phases (with given local proportion θ of the .rst material), in a stationary di.usion problem, is considered. The question of describing two columns of these matrices, or more precisely the set {(Ae, Af) : A ∈ 𝒦(θ)}, for two vectors e and f, is addressed.
