Presented Dimensions of Formal Power Series Rings |
| |
| Abstract: | Based on the research of finitely presented dimensions of modules and rings and by using the theory and method of homological algebra, presented dimensions of formal power series rings were described, and the relationship was obtained between presented dimensions of modules as well as between presented dimensions of rings when R,R x] ] are coherent rings. |
