Discrete approximate subgroups of Lie groups
… generalisations of Meyer's theorem in soluble Lie groups, in amenable locally compact groups and in higher-rank semi-simple algebraic groups. Along the way, we investigate properties of closed and discrete approximate subgroups of locally compact groups in general.

Applications of Lie Groups in Turbulence Modeling
Group analysis is applied to the general two-dimensional k-epsilon turbulence model. Symmetry algebras for the k-epsilon turbulence model have been calculated by Khor'kova. and Verbovetsky. This systematic approach is applied to the specific flow problem of turbulent submerged free plane jets. …

On properties of linear control systems on Lie groups
… properties of linear control systems on Lie groups as introduced by Ayala and Tirao in [AT99]. A linear control system _x0006_Σ Lie group G is defined by x' = X(x) + Σ<sup>k</sup><sub>j=1</sub> u<sub>j</sub>Y<sub>j</sub>(x), where the drift vector field X is an infinitesimal automorphism, …

Application of Lie Groups to Discretizing Nuclear Engineering Problems
In addition, a method using groups of point transformations along with Noether's theorem is shown to generate a conservation law that can be used to create a two-term recurrence relation which calculates numerically exact Green's functions in one dimension for the time-independent neutron diffusion …

Optimal control problems on lie groups with symmetry breaking cost functions
… smooth optimal control systems that evolve on Lie groups. Pontryagin's maximum principle allows us to search for local solutions of the optimal control problem by studying an associated Hamiltonian dynamical system. When the associated Hamiltonian function possess symmetries, we can often study …

Generalized Bäcklund-Darboux transformations for Coxeter-Toda systems on simple Lie groups

Equivariant coherent sheaves on the nilpotent cone for complex reductive Lie groups
Let G be a connected complex reductive Lie group. We propose a certain bijection between the set of dominant integral weights of G, and the set of pairs consisting of a nilpotent coadjoint orbit and a finite-dimensional irreducible representation of the isotropy group of the orbit. A constructive …
