Quasi-concavity for semilinear elliptic equations with non-monotone and anisotropic nonlinearities
<p>A boundary-value problem for a semilinear elliptic equation in a convex ring is considered. Under suitable structural conditions, any classical solution <mml:math alttext="$u$"> <mml:mi>u</mml:mi> </mml:math> lying between its (constant) boundary values i...
