GENERAL DECAY FOR A POROUS-THERMOELASTIC SYSTEM WITH MEMORY： THE CASE OF NONEQUAL SPEEDS＊

The aim of this paper is to establish a general decay result for a one-dimensional porous elastic system with different speeds of wave propagation in the presence of macrotem- perature effect and visco-porous dissipation.     

A GENERAL DECAY AND OPTIMAL DECAY RESULT IN A HEAT SYSTEM WITH A VISCOELASTIC TERM

We consider a quasilinear heat system in the presence of an integral term and establish a general and optimal decay result from which improves and generalizes several stability results in the literature.     

Some properties of the recursive projection and interpolation algorithms

The recursive projection algorithm (rpa), derived from the vectorSylvester identity, has a connection with the recursive interpolationalgorithm (ria). These algorithms have many applications andconnections with some other methods used in various areas ofnumerical analysis. The aim of this paper is to study some propertiesof these algorithms. We use properties of projectors, a matriximplementation and the Schur complement extended to the vectorcase, to give a result about their finite termination.
