Annotation | A theorem on the convergence of the solution of a three-layered difference scheme with two weights to the solution of an abstract ill-posed Cauchy problem is proved. The proof of convergence is based on the stability theorem for a three-layer difference scheme with two weights, which is based on the concepts of finite stability and on difference a priori weight estimates of the Carleman type. |

Keywords | ill-posed problem, difference scheme, finite stability, Carleman estimate, operator, $l - $ well-posed problem, convergence |
