  "abstract": "Recent experiments and computer simulations show that supercooled liquids around the glass transition temperature are \"dynamically heterogeneous\" [1]. Such heterogeneity is expected from the random first order transition theory of the glass transition. Using a microscopic approach based on this theory, we derive a relation between the departure from Debye relaxation as characterized by the $\\beta$ value of a stretched exponential response function $\\phi(t) =e^{-(t/ \\tau_{KWW})^{\\beta}}$, and the fragility of the liquid. The $\\beta$ value is also predicted to depend on temperature and to vanish as the ideal glass transition is approached at the Kauzmann temperature.",
