In a recent paper (R. Quintanilla, G. Saccomandi.

We proved a polynomial decay estimate for the solutions of this equation. In the present note we improve this result and we show a Phragmen-Lindelof alternative of exponential type.

Abstract
In a recent paper (R. Quintanilla, G. Saccomandi. Quarterly Applied Mathematics, 44, (2006) 547–560.) we investigated the spatial behavior of a linear equation of fourth order which models several mechanical situations where dispersive effects are taken into account. We proved a polynomial decay estimate for the solutions of this equation. In the present note we improve this result and we show a Phragmen-Lindelof alternative of exponential type.File in questo prodotto:
