A generalized k-Yamabe problem is considered in this paper. Denoting Ric and R the Ricci tensor and the scalar curvature of a Riemannian space (M, g) respectively, we consider the σ_k-type equation σ_k(λ_{st}) = const., where λ_{st} are the eigenvalues of the symmetric tensor sRic − tR g and σ_k is the k−th elementary symmetric polynomial. We show that the equation is solvable in a conformal class if sRic−tRg is in the convex cone Γ^+_k and 2t > s > 0.
