This structure-preserving factorization of the symplectic matrices immediately reveals two well-known features that (i) the determinant of any symplectic matrix is one and (ii) the matrix symplectic group is path connected, as well as a new feature that (iii) all the unit triangular symplectic ...
摘要: We show that for n>=3 the symplectic group Sp(n) is as a 2-compact group determined up to isomorphism by the isomorphism type of its maximal torus normalizer. This allows us to determine the integral homotopy type of Sp(n) among connected finite loop spaces with maximal torus....
The Ricci flow for simply connected nilmanifolds We prove that the Ricci flow g(t) starting at any metric on the euclidean space that is invariant by a transitive nilpotent Lie group N, can be obtained by... J Lauret - 《Communications in Analysis & Geometry》 被引量: 72发表: 2011年 ...
If is a polar representation with Cartan subspace and Weyl group , it is shown that there is a natural morphism of Poisson schemes . This morphism is conjectured to be an isomorphism of the underlying reduced varieties if is visible. The conjecture is proved for visible stable locally free po...
It is proved that any harmonic map ϕ : Ω→Sp(N) from a simply connected domain Ω ⊆R 2⋃ | ∞ | into the symplectic groupSp(N) ⊂U(2N) with finite uniton number can be factorized into a product of a finite number of symplectic unitons. Based on this factorization, it ...
The Symplectic Mapping Class Group of CP~2#nCP~2 with n ≤ 4 In this paper, we prove that the Torelli part of the symplec-tomorphism groups of the n-point (n ≤ 4) blow-ups of the projective plane is trivial. Consequ... JUN,Li,Tian-Jun,... - 《Michigan Mathematical Journal》 ...
