Möbius Transform and Its Applications in Physics
Li Weinan
CHINESE JOURNAL OF COMPUTATIONAL PHYSICS    1998, 15 (3): 331-336.  
Abstract499)      PDF (208KB)(1477)      
Möbius inverse formula is an old theorem in number theory. Professor Chen Nanxian extended it to ordinary function and presented a new method for solving many inversion problems in physics. This paper introduces Chen's theorem with a more comprehensible way and shows its vast range of application prospects by some concrete problems.

BOUNDARY ELEMENT METHOD FOR SOME POTENTIAL PROBLEMS
Li Weinan, Han Qingshu, Zhou Xueqiu
CHINESE JOURNAL OF COMPUTATIONAL PHYSICS    1997, 14 (6): 803-807.  
Abstract230)      PDF (209KB)(1005)      
Some potential problems are studied by applying boundary element method.The starting equation in the form of discretization is obtained by weighting residual.The computer software for numerical simulation has been provided.Numerical results conform to physics law and are satisfactory.
