Unifying Type-II Strings by Exceptional Groups. [PDF]

open access: yesPhysical Review Letters, 2017
We construct the exceptional sigma model: a two-dimensional sigma model coupled to a supergravity background in a manifestly (formally) E_{D(D)}-covariant manner.

Exceptional Groups

open access: yes, 2022
n this chapter we prove Cherlin’s conjecture for exceptional groups of Lie type. Our main result shows that, if G is an almost simple primitive group having socle an exceptional group of Lie type, then G is not binary. The proof uses some of the results in the previous chapters together with a detailed analysis of the maximal subgroups of G.

Chern-Simons theory with the exceptional gauge group as a refined topological string

open access: yesPhysics Letters B, 2020
We present the partition function of Chern-Simons theory with the exceptional gauge group on three-sphere in the form of a partition function of the refined closed topological string with relation 2τ=gs(1−b) between single Kähler parameter τ, string ...

On exceptional Lie geometries

open access: yesForum of Mathematics, Sigma, 2021
Parapolar spaces are point-line geometries introduced as a geometric approach to (exceptional) algebraic groups. We characterize a wide class of Lie geometries as parapolar spaces satisfying a simple intersection property.

Del Pezzo surfaces as Springer fibres for exceptional groups [PDF]

open access: yesProceedings of the London Mathematical Society, 2015
We show that simultaneous log resolutions of simply elliptic surface singularities can be constructed inside suitable stacks of principal bundles over elliptic curves.

An exceptional G(2) extension of the Standard Model from the correspondence with Cayley–Dickson algebras automorphism groups

open access: yesScientific Reports, 2021
In this article I propose a new criterion to extend the Standard Model of particle physics from a straightforward algebraic conjecture: the symmetries of physical microscopic forces originate from the automorphism groups of main Cayley–Dickson algebras ...

The Comparison of Compassion Fatigue of Exceptional Schools Teachers Based on Age, Gender, and Education in Hamadan [PDF]

open access: yesRavānshināsī-i Afrād-i Istis̠nāyī, 2020
Education in exceptional schools has its own difficulties and characteristics. The purpose of this study was to survey and compare the compassion fatigue of five groups of exceptional school teachers (including Mentally Retarded, Learning Disorders ...

Alternating subgroups of exceptional groups of Lie type [PDF]

open access: yes, 2015
In this paper, we examine embeddings of alternating and symmetric groups into almost simple groups of exceptional type. In particular, we prove that if the alternating or symmetric group has degree equal to 5, or 8 or more, then it cannot appear as the ...

Exceptional quantum groups

open access: yesPhysics Letters B, 1990
Abstract The braids Rˇ, the underlying structure of the Boltzmann weight of a solvable lattice model, are obtained for the fundamental representation of the exceptional quantum group E 6. The symmetry properties of quantum Clebsch-Gordan coefficients and the braids Rˇ under Weyl-reflection are noted.
