published in Aduance ACS Abstracts, February 15, 1994. 0095-233819411634-0421$04.50/0 Fueled by the intense activity in fullerene chemistry and intrinsically interesting geometrical and topological features of fullerenes, several studies have focused on the fascinating mathematical properties of fullerenes. These studies included graph theoretical computations of the characteristic polynomials,...

In this paper, a phase eld system of Penrose Fife type with non conserved order parameter is considered. A class of time discrete schemes for an initial boundary value problem for this phase eld system is presented. In three space dimensions, convergence is proved and an error estimate is derived. For one scheme, this error estimate is linear with respect to the time step size. 1 Introduction I...
