| Outline of Final Research Achievements |
We study orders and valuation rings. About order theory, ① we give the necessary and sufficient conditions for the ring of Morita contexts to be maximal orders in terms of modules theory.② we obtain that the necessary and sufficient conditions for skew polynomial rings and differential polynomial rings to be generalized Asano rings. ③we completely describe the structure of projective ideals in skew polynomial rings over hereditary rings, which leads us to find a new class of rings being called "generalized hereditary rings".
About the study of valuation rings,④we study prime ideals in graded extensions for crossed product algebras.
