AI中文摘要:
设R为交换诺特局部环,M与N是具有有限生成同调的R-复形。我们证明,导出Hom复形RHom(M,N)的同调维数公式,可在不附加经典结果中对M或N的维数的先验假设下成立。
英文摘要:
Let R be a commutative noetherian local ring and M and N be R-complexes with finitely generated homology. We prove that formulas for the homological dimensions of the derived Hom complex RHom(M,N), in terms of the homological dimensions of M and N, hold without the a priori assumptions on the dimensions of M or N present in classic results.
