2d mirror symmetry (or simply "mirror symmetry"), originating in the physics of two-dimensional supersymmetric QFT, has led to some of the most significant developments in algebra and geometry in the ...

There's a part of the brain that enables us to perceive magnitude -- we can compare loudness when hearing different tones or compare the number of dots in a group at a glance. Neuroscientists have ...

Dimsym is a program primarily for the determination of symmetries of differential equations. It also can be used to compute symmetries of distributions of vector fields or differential forms on finite ...

Non-parametric procedures, based on the empirical characteristic function, are proposed for estimating the centre δ of a symmetric distribution and for testing the hypothesis of symmetry around an ...

This article considers tests for symmetry of the one-dimensional marginal distribution of fractionally integrated processes. The tests are implemented by using an autoregressive sieve bootstrap ...

Receive emails about upcoming NOVA programs and related content, as well as featured reporting about current events through a science lens. Symmetry also has an aesthetic meaning, although this is ...

Abstract: Controllability and observability of multi-spin systems in architectures of various symmetries of coupling type and topology are investigated. We complement recent work of explicitly ...
