Abstract

In this paper we consider the Cauchy boundary value problem for the integro-differential equation

u_{t t} - m (\int_{Ω}^{} {| \nabla u |}^{2} d x) Δ u = 0 in Ω \times [0, T)

with a continuous nonlinearity

m : [0, + \infty) \to [0, + \infty)

. It is well known that a local solution exists provided that the initial data are regular enough. The required regularity depends on the continuity modulus of

m

. In this paper we present some counterexamples in order to show that the regularity required in the existence results is sharp, at least if we want solutions with the same space regularity of initial data. In these examples we construct indeed local solutions which are regular at

t = 0

, but exhibit an instantaneous (often infinite) derivative loss in the space variables.
