 Ding projective dimension of Gorenstein flat modules Bull. Korean Math. Soc. 2017 Vol. 54, No. 6, 1935-1950 https://doi.org/10.4134/BKMS.b160547Published online November 30, 2017 Junpeng Wang Northwest Normal University Abstract : Let $R$ be a Ding-Chen ring. Yang \cite{Yang2012} and Zhang \cite{Zhang2015} asked whether or not every $R$-module has finite Ding projective or Ding injective dimension. In this paper, we give a new characterization of that all modul\-es have finite Ding projective and Ding injective dimension in terms of the relationship between Ding projective and Gorenstein flat modules. We also give an example to obtain negative answer to the above question. Keywords : Ding projective module, Gorenstein flat module, Ding-Chen ring MSC numbers : 16E65, 18G20, 18G25 Full-Text :
