Kouémou-Patcheu, Solange Sharp energy decay estimates for a Petrovsky system with internal damping. (Estimations précises de la décroissance de l’énergie d’un système de Petrovsky avec amortissement interne.) (French. Abridged English version) Zbl 0838.34076 C. R. Acad. Sci., Paris, Sér. I 321, No. 6, 735-739 (1995). Summary: We establish precise estimates of the energy decay for a Petrovsky system, by applying a method based on a special integral. We prove how the damping term acts on the constants depending on the initial data in such estimates.
