  • A note on noncosingular lifting modules 
    Amouzegar Kalati, T.; Keskin Tütüncü, D. (Український математичний журнал, 2012)
    Let R be a right perfect ring. Let M be a noncosingular lifting module that does not have any relatively projective component. Then M has finite hollow dimension.
  • A study on dual square free modules 
    Medina-Bárcenas, M.; Keskin Tütüncü, D.; Kuratomi, Y. (Algebra and Discrete Mathematics, 2021)
    Let M be an H-supplemented coatomic module with FIEP. Then we prove that M is dual square free if and only if every maximal submodule ofM is fully invariant. Let M = ⊕ i∈I Mi be a direct sum, such that M is coatomic. Then ...
  • On dual Rickart modules and weak dual Rickart modules 
    Keskin Tütüncü, D.; Orhan Ertas, N.; Tribak, R. (Algebra and Discrete Mathematics, 2018)
    Let R be a ring. A right R-module M is called d-Rickart if for every endomorphism φ of M, φ(M) is a direct summand of M and it is called wd-Rickart if for every nonzero endomorphism φ of M, φ(M) contains a nonzero direct ...
