1. It is bijective if both injective and sujective.

2. Injective module is the important part of homological algebra.

3. Introduces and characterizes graded M - injective modules and graded V - modules, Obtains many interested properties.

4. Let me have a look You have acute injective conjunctivitis. You require some treatment.

4. Wish you will love sentencedict.com and make progress everyday!

5. Objective : To evaluate the efficacy of injective therapy for non parasitic hepatic cyst.

6. Xu Jinzhong proved module over commutative ring is injective if and only if it is flat.

7. Every module is a submodule an injective module and a homomorphic image of a projective module.

8. Let me have a look You have acute injective conjunctivitis. You need some treatment.

9. Injective modules play an important role in module theory and homological algebra.

10. Firstly, the regularity of right nonsingular AGP - injective rings are studied.

11. In this note, a constructive theorem for normal SM—algebra is given, and as applications of this theorem, Subdirectly irreducible normal SM—algebras and injective SM—algebras are also given.

12. Prepositive polymer slug displacement can decrease the effect by the formation heterogeneity, prevent the gas breakthrough and improve the displacement sweep efficiency of the injective gas.

13. Let S be a monoid, and P be any right quotient filter of S, we give the "ideal-congruent"discription of completely right P-injective monoids which generalizes the results of injective S-acts.

14. Furthermore, it is shown that every pure projective left R-module is closed under pure submodule if and only if every pure injective left R-module is closed under pure epimorphic image.

15. We also show that if R is a regular ring having a prime center then all simple left (right) R-modules are injective.

16. In this paper, we investigate the tilting modules, stable modules, directing modules, projective and injective modules of triangular matrix algebras.

17. By means of introducing semi - reflexive modules, we give the concept of SR - projective modules and SR - injective modules.

18. Proves weak reflexive singular operators constitute a closed and injective general operator ideal and the space ideal generated by them is also injective.
