Numerical analysis of an energy-like minimization method to solve Cauchy problem with noisy data
Résumé
This paper is concerned with solving Cauchy problem for elliptic equation by minimizing an energy-like error functional and by taking into account noisy Cauchy data. After giving some fundamental results, Cauchy problem is presented as an optimal control problem. Numerical convergence analysis is carried out and leads to an adapted stopping criteria for the minimization process depending on noise rate. Numerical examples involving smooth and singular data are presented.
