In this paper, for the solution of the torsion problem about the equation Δu = −2 with homogeneous Dirichlet boundary conditions in a bounded convex domain in ℝn, we find a superharmonic function which implies the strict concavity of ({u^{{1 over 2}}}) and give some convexity estimates. It is a generalization of Makar-Limanov’s result (Makar-Limanov (1971)) and Ma-Shi-Ye’s result (Ma et al. (2012)).
