本文证明了f-余倾斜余模的Bongartz引理,即一个偏f-余倾斜余模可以做成f-余倾斜余模.首先得到了/-余倾斜余模的性质以及C-余模和AT-模之间的函子同构.此外还研究了Hom-挠对和Hom-余倾斜余模.“,”In this paper,we prove the Bongartz's lemma of f-cotilting comodule which asserts that a partial f-cotilting comodule may always be completed to an f-cotilting comodule.As a first consequence,we obtain some characterisation of f-cotilting comodules and functorial isomorphisms between C-comodules and AT-modules.Among other things,we study Hom-torsion pairs and Hom-cotilting comodules.
