چکیده مقاله:
In this paper, we will have the different glance to the geometry of the isometry group of a Riemannian manifold. In fact, the (Lie) group of isometries of a Riemannian manifold M,g, I M, acts on M properly and this action is specified by giving the orbits of points of M as an immersed submanifold of it. These submanifolds intersect the other submanifolds, i.e., slices at the fixed points of the action transversely. In this way, M by a suitable fibration can be expressed in the letters of the quotients of I M and its slices as the fiber. Also, there is the explicit corresponding relation between their Lie algebras. On the other hand, another glance to tangent bundle TM as an associated bundle to the frame bundle M , LM, results to the one-to-one correspondence between the special GLm,R -equivariant functions and vector field M . This correspondence via a Lie algebra homomorphism between the Lie algebras of TM, LI M and M , translates the main tools of the geometry of TM to the ones of M . We reach to these fundamental and applied conclusions through this paper.
