Salti, M.Korunur, M.Acikgoz, I.Binbay, F.Pirinccioglu, N.2024-04-242024-04-2420141221-146Xhttps://hdl.handle.net/11468/21802In the present work, we classified the BKS-type (we refer to Bianchi-Kantowski-Sachs type spacetimes collectively as the BKS-type spacetimes) spacetimes (Bianchi type-V, Bianchi type-VI (m), Bianchi type-VI:(m), Kantowski-Sachs) according to their matter collineations when the energy-momentum tensor is degenerate and also when it is non-degenerate. We find that the dimension of matter collineations is infinite and we have improper matter collineations for the degenerate case (there are seven possibilities make the energy-momentum tensor to be degenerate). Next, for the non-degenerate case of the energy-momentum tensor, we obtain proper matter collineations and find the dimension of the group is finite.eninfo:eu-repo/semantics/closedAccessBianchi TypeKilling VectorsMatter SymmetriesCollineationArticle591-26578WOS:000333227700007Q3
