Action Integrals along Closed Isotopies in Coadjoint Orbits

چکیده

LetO be the orbit of η ∈ g∗ under the coadjoint action of the compact Lie group G. We give two formulae for calculating the action integral along a closed Hamiltonian isotopy on O. The first one expresses this action in terms of a particular character of the isotropy subgroup of η. In the second one is involved the character of an irreducible representation of G.

Coadjoint orbits of the group UT(7, K)

Orbits of the coadjoint action play an important role in harmonic analysis, theory of dynamic systems, noncommutative geometry. A.A. Kirillov’s orbit method allows to reduce the classification problem of unitary representations of nilpotent Lie groups to the classification of coadjoint orbits [1, 2]. This makes possible to solve the problems of representation theory in geometric terms of the or...

Adjoint and Coadjoint Orbits of the Poincaré Group

In this paper we give an effective method for finding a unique representative of each orbit of the adjoint and coadjoint action of the real affine orthogonal group on its Lie algebra. In both cases there are orbits which have a modulus that is different from the usual invariants for orthogonal groups. We find an unexplained bijection between adjoint and coadjoint orbits. As a special case, we c...

Coadjoint orbits of symplectic diffeomorphisms of surfaces and ideal hydrodynamics

We give a classification of generic coadjoint orbits for the groups of symplectomorphisms and Hamiltonian diffeomorphisms of closed symplectic surfaces. We also classify simple Morse functions on symplectic surfaces with respect to actions of those groups. This gives an answer to V.Arnold’s problem on invariants of generic isovorticed fields for 2D ideal fluids.

Numerical Integration of Lie-Poisson Systems While Preserving Coadjoint Orbits and Energy

In this paper we apply geometric integrators of the RKMK type to the problem of integrating Lie– Poisson systems numerically. By using the coadjoint action of the Lie group G on the dual Lie algebra g∗ to advance the numerical flow, we devise methods of arbitrary order that automatically stay on the coadjoint orbits. First integrals known as Casimirs are retained to machine accuracy by the nume...

Parametrizing Real Even Nilpotent Coadjoint Orbits Using Atlas

Suppose GR is the real points of a complex connected reductive algebraic group G defined over R. (The class of such groups is exactly the class treated by the software package atlas.) Write g R for the dual of the Lie algebra of GR and N R for the nilpotent elements in gR. Then GR acts with finitely many orbits on N via the coadjoint action, and it is clearly very desirable to parametrize these...
