## Abstract In this paper we consider the non‐linear wave equation __a,b__>0, associated with initial and Dirichlet boundary conditions. We prove, under suitable conditions on __α,β,m,p__ and for negative initial energy, a global non‐existence theorem. This improves a result by Yang (__Math. Meth

In this paper, following the ideas of Lax, we prove a blow-up result for a class of solutions of the equation & -&x -&+xx -= 0, corresponding, in certain cases, to the development of a singularity in the second derivatives of 4. These solutions solve locally (in time) the Cauchy problem for smooth i
## SUMMARY In this paper, we consider the problem of existence of certain global solutions for general discrete‐time backward nonlinear equations, defined on infinite dimensional ordered Banach spaces. This class of nonlinear equations includes as special cases many of the discrete‐time Riccati equ
We investigate the set of all positive solutions of a semilinear equation Lu = ψ(u) where L is a second-order elliptic differential operator in a domain E of R d or, more generally, in a Riemannian manifold and ψ belongs to a wide class of convex functions that contains ψ(u) = u α for all α > 1. We
