Outcome Based Subgroup Analysis: A Neglected Concern. [PDF]
, 2009 A subgroup of clinical trial subjects identified by baseline characteristics is a proper subgroup while a subgroup determined by post randomization events or measures is an improper subgroup.

4d N = 3 $$ \mathcal{N}=3 $$ indices via discrete gauging
Journal of High Energy Physics, 2018 A class of 4d N = 3 $$ \mathcal{N}=3 $$ SCFTs can be obtained from gauging a discrete subgroup of the global symmetry group of N = 4 $$ \mathcal{N}=4 $$ Super Yang-Mills theory.

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 ...

Generalised verification of the observer property in discrete event systems [PDF]
, 2012 The observer property is an important condition to be satisfied by abstractions of Discrete Event Systems (DES) models. This paper presents a generalised version of a previous algorithm which tests if an abstraction of a DES obtained through natural ...

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.

Conflict-preserving abstraction of discrete event systems using annotated automata [PDF]
, 2012 This paper proposes to enhance compositional verification of the nonblocking property of discrete event systems by introducing annotated automata. Annotations store nondeterministic branching information, which would otherwise be stored in extra states ...

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

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 ...
