quotient category
Examples
- Similarly , cokernels of the flat envelope of a finitely gener - ated coreduced gorenstein flat module is also a finitely generated coreduced gorenstein flat module , moreover the flat envelope of the former is the flat cover of the latter . and then we prove that over these rings , in quotient categories mod every finitely generated module has a finitely generated coreduced gorenstein flat preenvelope , and its two such preenvelopes are isomorphic
接着证明了这类环上每个模的极小平坦分解式的合冲模从第n个起都是有限生成的上约化的gorenstein平坦模，最后证明了在这类环上，商范畴dlaa中每个有限生y成模都有有限生成的上约化的gorenstein平坦包，并且这种盖在同构意义下是唯一的
