Lie Groups,f differentiable manifold. Two examples are the isometries of a Riemannian manifold and the symmetries of a second-order ODE, considered in Sects. . and ., respectively. In this chapter we shall study these groups by themselves, combining their algebraic and differentiable structures. One of the mai极肥胖 发表于 2025-3-27 02:48:53

Graduate Texts in Contemporary Physicsnd ., respectively. In this chapter we shall study these groups by themselves, combining their algebraic and differentiable structures. One of the main results of this combination is the fact that each of these groups has an associated Lie algebra which almost entirely determines the group.labile 发表于 2025-3-28 03:19:35
