    Notes: Abstract Various, but closely related, forms of a Phragmén-Lindelöf principle are established for certain classes of semi-linear elliptic equations (including systems) defined on a half-cylinder. For example, it is shown that under either homogeneous Dirichlet or Neumann lateral boundary conditions, the smooth solution either fails to exist globally, or when it does exist globally it must tend asymptotically to zero with increasingly large distance along the cylinder from the base. For uniformly elliptic equations, the decay to zero is at least exponential. The method employed relies upon cross-sectional estimates and is additionally applicable to both the finite and whole cylinder. In the latter case, global existence fails for all non-trivial solutions.

    Notes: Summary A rectangular strip, consisting of homogeneous, isotropic, elastic material, is in an equilibrium state of plane stress, due to actions applied to a pair of opposite edges, the remaining pair being traction-free. The convexity of certain cross-sectional measures of stress is established; and a generalized convexity property is also established for one such measure, leading to an explicit decay estimate for the measure in the case of a semi-infinite strip, one end of which is subjected to a self-equilibrated load.

    Description / Table of Contents: Résumé Nous obtenons des bornes superieures pour la rigidité à la torsion d'un cylindre droit isotrope dont chaque extrémité est maintenue dans un plan rigide; ces bornes s'expriment à l'aide de la rigidité à la torsion de Saint-Venant, du moment polaire d'inertie de la section et de la valeur propre fondamentale de la membrane libre, ainsi que la longueur du cylindre et des constantes d'élasticité. Elles peuvent servir à démontrer que ces deux rigidités coincident quand la longueur du cylindré tend vers l'infini. Nous étudions aussi d'autres implications des bornes.
    Notes: Abstract We obtain upper bounds for the torsional rigidity of an isotropic right cylinder whose ends are restrained against warping in terms of the Saint-Venant torsional rigidity, the polar moment of inertia and the lowest free membrane eigenvalue of the cross-section, the length of the cylinder and the elastic constants. They may be used to show that the two torsional rigidities tend to coincidence as the cylinder becomes infinitely long. Various other implications of the bounds are also discussed.
