As a consequence, optimal functions and sharp constants are computed in the symmetry region. The result solves a longstanding conjecture on the optimal symmetry range.\n  As a byproduct of our method we obtain sharp estimates for the principal eigenvalue of Schr\\\"odinger operators on some non-flat non-compact manifolds, which to the best of our knowledge are new.\n  The method relies on generalized entropy functionals for nonlinear diffusion equations.
