Minimal semi-flat-cotorsion replacements and cosupport
Nakamura, Tsutomu; Thompson, Peder (Journal article; Peer reviewed, 2020)Over a commutative noetherian ring Rof finite Krull dimension, we show that every complex of flat cotorsion R-modules decomposes as a direct sum of a minimal complex and a contractible complex. Moreover, we define the ...
