Abstract
In this paper we construct upper and lower solutions for a class of parabolic initial-boundary value problems in terms of the solution $\psi(x)$ of the St-Venant problem and first eigenvalue problem. These bounds are sharp in the sense that they coincide with the exact solution in particular situations.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
