Symmetry group at future null infinity II: Vector theory
Journal of High Energy Physics, 2023 In this paper, we reduce the electromagnetic theory to future null infinity and obtain a vector theory at the boundary. We compute the Poincaré flux operators which could be generalized.

Symmetry groups of boolean functions
European Journal of Combinatorics, 2014 We prove that every abelian permutation group, but known exceptions, is the symmetry group of a boolean function. This solves the problem posed in the book by Clote and Kranakis. In fact, our result is proved for a larger class of groups, namely, for all groups contained in direct sums of regular groups.

Symmetry group at future null infinity III: Gravitational theory
Journal of High Energy Physics, 2023 We reduce the gravitational theory in an asymptotically flat spacetime to future null infinity. We compute the Poincaré flux operators at future null infinity and construct the supertranslation and superrotation generators.

Field theories with higher-group symmetry from composite currents
Journal of High Energy Physics, 2021 Higher-form symmetries are associated with transformations that only act on extended objects, not on point particles. Typically, higher-form symmetries live alongside ordinary, point-particle (0-form), symmetries and they can be jointly described in ...

Structures of coincidence symmetry groups [PDF]
Acta Crystallographica Section A Foundations of Crystallography, 2006 The structure of the coincidence symmetry group of an arbitrary n-dimensional lattice in the n-dimensional Euclidean space is considered by describing a set of generators. Particular attention is given to the coincidence isometry subgroup (the subgroup formed by those coincidence symmetries that are elements of the orthogonal group).

, 2004 The concepts of symmetry and symmetry groups are at the heart of several developments in modern theoretical and mathematical physics. The present paper is devoted to a number of selected topics within this framework: Euclidean and rotation groups; the properties of fullerenes in physical chemistry; Galilei, Lorentz and Poincare groups; conformal ...

Topological Phases Protected by Point Group Symmetry
Physical Review X, 2017 We consider symmetry-protected topological (SPT) phases with crystalline point group symmetry, dubbed point group SPT (pgSPT) phases. We show that such phases can be understood in terms of lower-dimensional topological phases with on-site symmetry and ...

Extracta MathematicaeLet d ≥ 2. In this paper we prove that Id(ℓ, a) fills Rd face–to–face by translations. We prove that the symmetry group of Id(ℓ, a) contains the product of cyclic groups Cd × C2 as a subgroup.

On the Virasoro Structure of Symmetry Algebras of Nonlinear Partial Differential Equations
Symmetry, Integrability and Geometry: Methods and Applications, 2006 We discuss Lie algebras of the Lie symmetry groups of two generically non-integrable equations in one temporal and two space dimensions arising in different contexts.

Targeting high symmetry in structure predictions by biasing the potential energy surface
Physical Review Research, 2023 Ground-state structures found in nature are, in many cases, of high symmetry. But structure prediction methods typically render only a small fraction of high-symmetry structures.
