【Abstract】 In this paper,the inverse problem to identify the coefficient v in the steady-state diffusion equation-div(v grad u)=f for two dimensional orthotropic medium is discussed.We construct an associated functional,and prove some properties of the functional.Under certain conditions,we seek to identify the coefficient v by minimization of the above functional.更多还原
