Differences in the visual perception of symmetric patterns in orangutans (Pongo pygmaeus abelii) and two human cultural groups: a comparative eye-tracking study

Frontiers in Psychology, 2016
Symmetric structures are of importance in relation to aesthetic preference. To investigate whether the preference for symmetric patterns is unique to humans, independent of their cultural background, we compared two human populations with distinct ...

Design and synthesis of C3-symmetric molecules bearing propellane moieties via cyclotrimerization and a ring-closing metathesis sequence

Beilstein Journal of Organic Chemistry, 2018
We have developed an efficient synthetic strategy to assemble C3-symmetric molecules containing propellane moieties as end groups and a benzene ring as a central core. The synthesis of these C3-symmetric molecules involves simple starting materials.

Conjectures on the normal covering number of finite symmetric and alternating groups [PDF]

International Journal of Group Theory, 2014
Let gamma(Sn) be the minimum number of proper subgroups Hi, i = 1,...,ell, of the symmetric group Sn such that each element in Sn lies in some conjugate of one of the Hi.

Survey on real forms of the complex A2(2)-Toda equation and surface theory

Complex Manifolds, 2019
The classical result of describing harmonic maps from surfaces into symmetric spaces of reductive Lie groups [9] states that the Maurer-Cartan form with an additional parameter, the so-called loop parameter, is integrable for all values of the loop ...

Dunkl Operators and Canonical Invariants of Reflection Groups

Symmetry, Integrability and Geometry: Methods and Applications, 2009
Using Dunkl operators, we introduce a continuous family of canonical invariants of finite reflection groups. We verify that the elementary canonical invariants of the symmetric group are deformations of the elementary symmetric polynomials.

Isomorphisms of algebras of symmetric functions on spaces $\ell_p$

Математичні Студії
The work is devoted to the study of algebras of entire symmetric functions on some Banach spaces of sequences. A function on a vector space is called symmetric with respect to some fixed group $G$ of operators acting on this space, or $G$-symmetric, if ...

CP-like symmetry with discrete and continuous groups and CP violation/restoration

Journal of High Energy Physics
We study physical implications of general CP symmetry including CP-like symmetry. Various scattering amplitudes of CP asymmetry are calculated in CP-like symmetric models.
