ON SUPER QUASI EINSTEIN MANIFOLDPratyay Debnath and Arabinda KonarHooghly Engineering and Technology College, Pipulpati, Hooghly, 712103, India and Department of Mathematics, University of Kalyani, Nadia, 741235, IndiaAbstract: We study super quasi Einstein manifold and viscous fluid super quasi Einstein spacetime. The existence of super quasi Einstein manifold and viscous fluid super quasi Einstein spacetime are shown by two closely related examples. Also, some results involving super quasi Einstein manifold, pseudo quasi Einstein manifold and quasi Einstein manifold are established. Finally, the bounds of the cosmological constant in a viscous fluid super quasi Einstein spacetime are deduced. Keywords: quasi Einstein manifold, parallel vector field, pseudo quasi Einstein manifold, viscous fluid spacetime Classification (MSC2000): 53C50, 53C25, 53B30; 53C80, 53B50 Full text of the article: (for faster download, first choose a mirror)
