BPS Center Vortices in Nonrelativistic SU(N) Gauge Models with Adjoint Higgs Fields

Advances in High Energy Physics, 2015
We propose a class of SU(N) Yang-Mills models, with adjoint Higgs fields, that accept BPS center vortex equations. The lack of a local magnetic flux that could serve as an energy bound is circumvented by including a new term in the energy functional ...

Adjoint Majorana QCD2 at finite N

Journal of High Energy Physics, 2023
The mass spectrum of 1 + 1-dimensional SU(N) gauge theory coupled to a Majorana fermion in the adjoint representation has been studied in the large N limit using Light-Cone Quantization.

Nevanlinna representations in several variables [PDF]

, 2012
We generalize two integral representation formulae of Nevanlinna to functions of several variables. We show that for a large class of analytic functions that have non-negative imaginary part on the upper polyhalfplane there are representation formulae in

Dynamic Behavior of a Two‐Degree‐of‐Freedom System With Electromagnetic Interaction via a Skew‐Symmetric Matrix

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT This paper analyzes the dynamic behavior of a two‐degree‐of‐freedom system subjected to electromagnetic interaction modelled through a skew‐symmetric coupling matrix. The system comprises two mechanically independent oscillators coupled by velocity‐dependent electromagnetic forces.

Representation of SU(infinity) Algebra for Matrix Models

, 2002
We investigate how the matrix representation of SU(N) algebra approaches that of the Poisson algebra in the large N limit. In the adjoint representation, the (N^2-1) times (N^2-1) matrices of the SU(N) generators go to those of the Poisson algebra in the

A Note on the Existence and Optimal Control of Atangana–Baleanu Fractional Stochastic Integrodifferential System With Noninstantaneous Impulses

Optimal Control Applications and Methods, EarlyView.
Optimal Control of AB Caputo Fractional Stochastic Integrodifferential Control System with Noninstantaneous Impulses. ABSTRACT This study is concerned with the existence of mild solution and optimal control for the Atangana–Baleanu fractional stochastic integrodifferential system with noninstantaneous impulses in Hilbert spaces. We verify the existence

Embedding of the Georgi-Glashow SU(5) model in the superconformal algebra

Journal of High Energy Physics, 2023
We present a scheme to construct grand unified models based on the superconformal algebra and the inclusion of matter fields in the adjoint representation of supersymmetry. As an illustration, we implemented the Georgi-Glashow SU(5) model.

The adjoint representation of group algebras and enveloping algebras [PDF]

Publicacions Matemàtiques, 1992
In this paper we study the Hopf adjoint action of group algebras and enveloping algebras. We are particularly concerned with determining when these representations are faithful. Delta methods allow us to reclute the problem to certain better behaved subalgebras.
