摘要

Consider an operator equation (*) B(u)f=0B(u)-f=0 in a real Hilbert space. Let us call this equation ill-posed if the operator B(u)B'(u) is not boundedly invertible, and well-posed otherwise. The DSM (dynamical systems method) for solving equation (*) consists of a construction of a Cauchy problem, which has the following properties: 1) it has a global solution for an arbitrary initial data, 2) this solution tends to a limit as time tends to infinity, 3) the limit is the minimal-norm solution to the equation B(u)=fB(u)=f. A global convergence theorem is proved for DSM for equation (*) with monotone Cloc2C_{loc}^2 operators BB.
