Spherical surfaces in R 3 are discretized by piecewise linear triangle.
Dynamical variables are the positions X of the vertices and the triangulation g .
The action of the model is sum of area energy and bending energy times bending rigidity b . The bending energy and the specific heat are measured, and the critical exponents of the phase transitions are obtained by a finite-size scaling technique. We find that our model of fluid membrane undergoes a second order phase transition. Back to Contents of Vol.
