The R ∞ R_{\infty} property for nilpotent quotients of Generalized Solvable Baumslag–Solitar groups

open access: yesJournal of Group Theory, 2023
Abstract We say a group 𝐺 has property R ∞ R_{\infty} if the

Lie rank in groups of finite Morley rank with solvable local subgroups [PDF]

open access: yes, 2013
We prove a general dichotomy theorem for groups of finite Morley rank with solvable local subgroups and of Pr\"ufer p-rank at least 2, leading either to some p-strong embedding, or to the Pr\"ufer p-rank being exactly ...

Formality and hard Lefschetz property of aspherical manifolds [PDF]

open access: yes, 2012
For a Lie group $G=\R^{n}\ltimes_{\phi}\R^{m}$ with the semi-simple action $\phi:\R^{n}\to {\rm Aut}(\R^{m})$, we show that if $\Gamma$ is a finite extension of a lattice of $G$ then $K(\Gamma, 1)$ is formal.

Very nilpotent basis and n-tuples in Borel subalgebras [PDF]

open access: yes, 2010
A (vector space) basis B of a Lie algebra is said to be very nilpotent if all the iterated brackets of elements of B are nilpotent. In this note, we prove a refinement of Engel's Theorem.

A Parafermionic Generalization of the Jaynes Cummings Model [PDF]

open access: yes, 2014
We introduce a parafermionic version of the Jaynes Cummings Hamiltonian, by coupling $k$ Fock parafermions (nilpotent of order $F$) to a 1D harmonic oscillator, representing the interaction with a single mode of the electromagnetic field.

Central theorems for cohomologies of certain solvable groups [PDF]

open access: yes, 2015
We show that the group cohomology of torsion-free virtually polycyclic groups and the continuous cohomology of simply connected solvable Lie groups can be computed by the rational cohomology of algebraic groups. Our results are generalizations of certian

Quasi-classical Lie algebras and their contractions [PDF]

open access: yes, 2006
After classifying indecomposable quasi-classical Lie algebras in low dimension, and showing the existence of non-reductive stable quasi-classical Lie algebras, we focus on the problem of obtaining sufficient conditions for a quasi-classical Lie algebras ...

On Lie-algebraic solutions of the type IIB matrix model

open access: yes, 2011
A systematic search for Lie algebra solutions of the type IIB matrix model is performed. Our survey is based on the classification of all Lie algebras for dimensions up to five and of all nilpotent Lie algebras of dimension six. It is shown that Lie-type
