摘要：
The Laplace-Beltrami operator is the most important second order differential operator on a smooth surface. It is well-known that the convergence problem of the Laplace-Beltrami operators plays an essential role in the convergence analysis of the numerical simulations of some important geometric partial differential equations which involve the operator. In this talk we shall discuss a simple convergent algorithm to compute discrete Laplace-Beltrami operators acting on functions over smooth surfaces.
