Abstract(in English) This paper present first show CM test algorithms to find elliptic curves with CM without restriction on class numbers. In the second part, we show how to construct ring class fields from ray class fields. Finally, an algorithm for lifting the ring class equations from small finite fields is presented. All calculations in these algorithms are simple and easy to implement. Since there is only algebraic manipulations involved, no care is needed about approximation errors control during the calculations.
