A Rigidity Theorem for Discrete Subgroups [PDF]

Transactions of the American Mathematical Society, 1967
0. Introduction. Let G denote an analytic group and let P c G denote a discrete subgroup. A left invariant Haar measure on G then induces a measure on G/r, which is determined up to a positive constant. We let v denote one such induced measure on G/P. DEFINITION 0.1. F is called a lattice, in case v(G/f) < oo.

A generalization of decomposition in orbifolds

Journal of High Energy Physics, 2021
This paper describes a generalization of decomposition in orbifolds. In general terms, decomposition states that two-dimensional orbifolds and gauge theories whose gauge groups have trivially-acting subgroups decompose into disjoint unions of theories ...

ON DISCRETENESS OF SUBGROUPS OF QUATERNIONIC HYPERBOLIC ISOMETRIES [PDF]

Bulletin of the Australian Mathematical Society, 2019
Let $\mathbf{H}_{\mathbb{H}}^{n}$ denote the $n$-dimensional quaternionic hyperbolic space. The linear group $\text{Sp}(n,1)$ acts on $\mathbf{H}_{\mathbb{H}}^{n}$ by isometries. A subgroup $G$ of $\text{Sp}(n,1)$ is called Zariski dense if it neither fixes a point on $\mathbf{H}_{\mathbb{H}}^{n}\cup \unicode[STIX]{x2202}\mathbf{H}_{\mathbb{H}}^{n ...

Gauge origin of discrete flavor symmetries in heterotic orbifolds

Physics Letters B, 2014
We show that non-Abelian discrete symmetries in orbifold string models have a gauge origin. This can be understood when looking at the vicinity of a symmetry enhanced point in moduli space.

Notes on two-dimensional pure supersymmetric gauge theories

Journal of High Energy Physics, 2021
In this note we study IR limits of pure two-dimensional supersymmetric gauge theories with semisimple non-simply-connected gauge groups including SU(k)/ℤ k , SO(2k)/ℤ2, Sp(2k)/ℤ2, E 6/ℤ3, and E 7/ℤ2 for various discrete theta angles, both directly in the

Quantum computation of discrete logarithms in semigroups

Journal of Mathematical Cryptology, 2014
We describe an efficient quantum algorithm for computing discrete logarithms in semigroups using Shor's algorithms for period finding and the discrete logarithm problem as subroutines.

N = 3 SCFTs in 4 dimensions and non-simply laced groups

Journal of High Energy Physics, 2020
In this paper we discuss various N = 3 SCFTs in 4 dimensions and in particular those which can be obtained as a discrete gauging of an N = 4 SYM theories with non- simply laced groups.

A monograph on the classification of the discrete subgroups of SU(4) [PDF]

Journal of High Energy Physics, 2001
We here present, in modern notation, the classification of the discrete finite subgroups of SU(4) as well as the character tables for the exceptional cases thereof (Cf. https://github.com/yanghuihe/SU4Subgroups). We hope this catalogue will be useful to works on string orbifold theories, quiver theories, WZW modular invariants, Gorenstein resolutions ...

Prominent corneal nerves in pure mucosal neuroma syndrome, a clinical phenotype distinct from multiple endocrine neoplasia type 2B

BMC Ophthalmology, 2023
Background Pure mucosal neuroma syndrome (MNS), an autosomal dominant neurocutaneous disorder, is a rare discrete subgroup in multiple endocrine neoplasia (MEN) type 2B, which present without associated endocrinopathies of MEN2B but with typical physical
