On the stability estimation of analytic continuation for potential field

  • Xu Dinghua
  • Cheng Jin
  • Li Mingzhong


This paper discusses the stability of solutions to a class of Cauchy problems for Laplace equations under two kinds of nonclassical circumstances. By means of conformal mapping and Tikhonov, Luan Wengui and Yamamoto's methods for solving ill-posed problems respectively, the stability estimations of weighted Hölder type and logarithmic type, have been obtained accordingly.

Key words

Cauchy problems for Laplace equations analytic continuation of potential field ill-posed problems stability estimation
