The linear form of the Klein-Gordon equation for a scalar field with both minimally and conformally coupled cases in de Sitter and flat metrics are also calculated.}, number={1}, journal={Journal of Theoretical and Applied Physics}, publisher={OICC Press}, author={Tanhayi, Mohammad Reza and Mirabi, Sepideh}, year={2023}, month={Nov.}, keywords={Momentum tensor in curved space, De Sitter spacetime, Energy, Gordon equation, Klein} }
