Clones of 2-step nilpotent groups
We prove that if G is a 2-step nilpotent group, then an operation f : Gn → G is a local term operation of G if and only if f preserves the subgroups of G4.
متن کامل2-step Nilpotent Lie Groups Arising from Semisimple Modules
Let G0 denote a compact semisimple Lie algebra and U a finite dimensional real G0 module. The vector space N0 = U ⊕ G0 admits a canonical 2-step nilpotent Lie algebra structure with [N0,N0] = G0 and an inner product 〈, 〉, unique up to scaling, for which the elements of G0 are skew symmetric derivations of N0. Let N0 denote the corresponding simply connected 2-step nilpotent Lie group with Lie a...
متن کاملRiemannian Submersions and Lattices in 2-step Nilpotent Lie Groups
We consider simply connected, 2-step nilpotent Lie groups N, all of which are diffeomorphic to Euclidean spaces via the Lie group exponential map exp : ˆ → N. We show that every such N with a suitable left invariant metric is the base space of a Riemannian submersion ρ : N* → N, where the fibers of ρ are flat, totally geodesic Euclidean spaces. The left invariant metric and Lie algebra of N* ar...
متن کاملGeometry of Nilpotent and Solvable Groups
(Answer 1) By defining a Cayley graph. Let S be a finite generating set for G , such that S−1 = {s−1 | s ∈ S} = S and 1 ̸∈ S . NB From now on we always assume that generating sets of the group that we consider satisfy the above. The Cayley graph Cayley(G,S) of G with respect to the generating set S is a non-oriented graph defined as follows: • its set of vertices is G ; • every pair of elements ...
