Let Omega subsetR^N be a bounded smooth domain. We investigate theudeffect of the mean curvature of the boundary partial Omega on the behaviour of theudsolution to the homogeneous Dirichlet boundary value problem for the equationudDelta u + f(u) = 0. Under appropriate growth conditions on f(t) as t approachesudzero, we find asymptotic expansions up to the second order of the solution inudterms of the distance from x to the boundary partial Omega.
