Monte Carlo Simulations for the Slow Relaxations of Crumpled Surfaces
  In this paper we study crumpled surfaces through Monte Carlo Simulations. The crumpled surface is represented by a cluster of spins pointing up and spins pointing down represent the air both inside and around the surface. We follow the time dynamics of this fractal structure and we have shown that it presents a stretched exponential behaviour.
