Outline of Final Research Achievements

The purpose of this study was to improve the Hrushovski construction. Then I proved that every generic structure had near model completeness. On the other hand, there are some generic structures whose theories are not model complete. I obtained a characterization of model completeness in generic structures. Moreover, I proved that any generic structure with the full amalgamation was always stable.
