In this paper, the tilting theorem is generalized to the finitely generated torsionless module categories overπ coherent rings and relate this theory to duality theory.
本文建立了 π-凝聚环上有限生成无挠模范畴的 Tilting定理及相关的广义Morita对偶。

4) strongly coherent
强凝聚环
1.
This paper discussed the direct product and direct limitof left f-projective R-modules and proved that the direct product ofleft f-projective R-modules is left f-projective R-modules if and onlyif R is right strongly coherent.
该文讨论了f-投射模的直积和正向极限,证明了f-投射左R-模的直积是f-投射模的充要条件为R是右强凝聚环。

P-凝聚环
1.
Moreover,we introduce the concept of P-coherent rings.
并推广了左凝聚环的概念,引入了左P-凝聚环的概念,最后也用P-平坦模和P-内射模来刻画了左P-凝聚环。
补充资料:BCS凝聚能(BCScondensationenergy)
BCS凝聚能(BCScondensationenergy)
一般将T=0K时的超导基态能量Es(0)与正常态费米球分布能量En(0)之差称BCS凝聚能。由BCS理论给出:
Es(0)-En(0)=-N(0)Δ2(0)/2
由此可知,Es(0)<En(0),能隙2Δ(0)的出现,系统将从正常态转入超导态而发生超导相变。
