متن کاملGeometric symmetries on Lorentzian manifolds
Lie derivatives of various geometrical and physical quantities define symmetries and conformal symmetries in general relativity. Thus we obtain motions, collineations, conformal motions and conformal collineations. These symmetries are used not only to find new solutions of Einstein’s field equations but to classify the spaces also. Different classification schemes are presented here. Relations...
متن کاملOn Concircularly Φ−recurrent Para-sasakian Manifolds
A transformation of an n-dimensional Riemannian manifold M , which transforms every geodesic circle of M into a geodesic circle, is called a concircular transformation. A concircular transformation is always a conformal transformation. Here geodesic circle means a curve in M whose first curvature is constant and second curvature is identically zero. Thus, the geometry of concircular transformat...
