模的Rees代数与凝聚函子
Rees algebras of modules and coherent functors
摘要:
我们表明,里斯代数的模块的理论的几个属性变得更加透明的使用范畴的连贯函子,而不是直接与模块。特别地,我们证明了Rees代数是由相干函子的正则映射诱导的。
英文摘要:
We show that several properties of the theory of Rees algebras of modules become more transparent using the category of coherent functors rather than working directly with modules. In particular, we show that the Rees algebra is induced by a canonical map of coherent functors.
