Quasi-concavity for semilinear elliptic equations with non-monotone and anisotropic nonlinearities
<p/> <p>A boundary-value problem for a semilinear elliptic equation in a convex ring is considered. Under suitable structural conditions, any classical solution <inline-formula><graphic file="1687-2770-2006-80347-i1.gif"/></inline-formula> lying between its (c...
