United Nations Educational, Scientific and Cultural Organization and International Atomic Energy Agency THE ABDUS SALAM INTERNATIONAL CENTRE FOR THEORETICAL PHYSICS SOME RESULTS ON THE ASYMPTOTIC BEHAVIOUR OF HYPERBOLIC SINGULAR PERTURBATIONS PROBLEMS

Anisotropic singular perturbations of linear hyperbolic problems are considered. A description of the asymptotic behaviour of the solution as ε → 0 is given. In the case of cylindrical domains, we improve the rate of convergence in regions far from the lateral boundary.

United Nations Educational Scientific and Cultural Organization and International Atomic Energy Agency THE ABDUS SALAM INTERNATIONAL CENTRE FOR THEORETICAL PHYSICS SELF-CONSISTENT NONLINEARLY POLARIZABLE SHELL-MODEL DYNAMICS FOR FERROELECTRIC MATERIALS

We investigate the dynamical properties of the polarizable shell-model with a symmetric double Morse-type electron-ion interaction in one ionic species. A variational calculation based on the Self-Consistent Einstein Model (SCEM) shows that a theoretical ferroelectric (FE) transition temperature can be derived which demonstrates the presence of a first-order phase transition for the potassium s...
