Towards semi-classical analysis for sub-elliptic operators

Bruno Pini Mathematical Analysis Seminar, 2022
We discuss the recent developments of semi-classical and micro-local analysis in the context of nilpotent Lie groups and for sub-elliptic operators.

Generalized nilpotent braces and nilpotent groups [PDF]

International Journal of Group Theory, 2023
The authors give a brief survey of some results concerning nilpotent braces and their generalizations. Various results concerning $\star$-hypercentral and locally $\star$-nilpotent braces are given.

Quiver theories for moduli spaces of classical group nilpotent orbits [PDF]

Journal of High Energy Physics, 2016
We approach the topic of Classical group nilpotent orbits from the perspective of the moduli spaces of quivers, described in terms of Hilbert series and generating functions.

Generalized Analogs of the Heisenberg Uncertainty Inequality [PDF]

, 2015
We investigate locally compact topological groups for which a generalized analogue of Heisenberg uncertainty inequality hold. In particular, it is shown that this inequality holds for $\mathbb{R}^n \times K$ (where $K$ is a separable unimodular locally ...

Nilpotent fuzz [PDF]

Reports on Mathematical Physics, 2008
We present a construction of the formalism where fundamental variables are nilpotent, but in contrast to the supermathematics, commutative. This gives another possibility to realize classically the Pauli exclusion principle. We sketch the relevant formalism and discuss simple model of the nilpotent oscillator to illustrate the generalized nilpotent ...

Approximate lattices and Meyer sets in nilpotent Lie groups [PDF]

Discrete Analysis, 2018
We show that uniform approximate lattices in nilpotent Lie groups are subsets of model sets. This extends Y.Meyer's theorem about quasi-crystals in Euclidean spaces. We derive from this structure theorem a characterisation of connected, simply connected,

Strongly 2T - Clean Rings [PDF]

Al-Rafidain Journal of Computer Sciences and Mathematics
An element a in a ring R is referred to be strongly 2T-clean (2 – STC element for short), a = Ω-Λ+u, where Ω,Λ are idempotent elements and u is a unit elements of order three.

On n-Nilpotent Groups and n-Nilpotency of n-Abelian Groups [PDF]

Mathematics Interdisciplinary Research, 2020
The concept of n-nilpotent groups was introduced by Moghaddam and Mashayekhy in 1991 which is in a way a generalized version of the notion of nilpotent groups.

Strongly Ad-Nilpotent Elements of the Lie Algebra of Upper Triangular Matrices

Journal of Mathematics, 2022
In this paper, the strongly ad-nilpotent elements of the Lie algebra tn,ℂ of upper triangular complex matrices are studied. We prove that all the nilpotent matrices in tn,ℂ are strongly ad-nilpotent if and only if n≤6. Additionally, we prove that all the

Fitting quotients of finitely presented abelian-by-nilpotent groups [PDF]

, 2013
We show that every finitely generated nilpotent group of class 2 occurs as the quotient of a finitely presented abelian-by-nilpotent group by its largest nilpotent normal subgroup.Comment: This second version takes into account the suggestions by the ...
