On subsemigroups of semisimple Lie groups

open access: yesProceedings of the Indian Academy of Sciences: Mathematical Sciences, 1995
Let \(G\) be a connected semisimple Lie group and \(S\) a subsemigroup of \(G\). Suppose that \(\mathfrak g\) is the Lie algebra of \(G\) and \({\mathfrak g}={\mathfrak k}+{\mathfrak p}\) a Cartan decomposition. The authors prove that \(S\) is a group if it is biinvariant under the analytic subgroup \(K\) of \(G\) with Lie algebra \(\mathfrak k ...

A note on $2$-plectic vector spaces [PDF]

open access: yesJournal of Mahani Mathematical Research, 2023
Among the $2$-plectic structures on vector spaces, the canonical ones and the $2$-plectic structures induced by the Killing form on semisimple Lie algebras are more interesting.

Coadjoint semi-direct orbits and Lagrangian families with respect to Hermitian form

open access: yesRevista Integración, 2023
We use the underlying structure of then coadjoint orbits of a semidirect product of a connected Lie group and a vector space to obtain families of Lagrangian submanifolds in the adjoint orbits of complex semisimple Lie groups with respect to the ...

On the derived Lusztig correspondence

open access: yesForum of Mathematics, Sigma, 2023
Let G be a connected reductive group, T a maximal torus of G, N the normalizer of T and $W=N/T$ the Weyl group of G. Let ${\mathfrak {g}}$ and ${\mathfrak {t}}$ be the Lie algebras of G and T. The affine variety $\mathfrak {car}={

Linear flows on compact, semisimple Lie groups: stability and periodic orbits

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2021
Our first purpose is to study the stability of linear flows on real, connected, compact, semisimple Lie groups. Our second purpose is to study periodic orbits of linear and invariant flows.

Electrical network and Lie theory [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2014
Curtis-Ingerman-Morrow studied the space of circular planar electrical networks, and classified all possible response matrices for such networks. Lam and Pylyavskyy found a Lie group $EL_{2n}$ whose positive part $(EL_{2n})_{\geq 0}$ naturally acts on ...

How to perform the coherent measurement of a curved phase space by continuous isotropic measurement. I. Spin and the Kraus-operator geometry of $\mathrm{SL}(2,\mathbb{C})$ [PDF]

open access: yesQuantum, 2023
The generalized $Q$-function of a spin system can be considered the outcome probability distribution of a state subjected to a measurement represented by the spin-coherent-state (SCS) positive-operator-valued measure (POVM).
