             ``Ill-posed Problems and A Priori Information''


¡ãAbstarct¡ä
In the presentation I shall describe how to use typical a priori information
(compactness of a set of solutions, sourcewise representation with completely
continuous operator) for constructing effective regularizing algorithms and 
error estmation in ill-posed problems.
