Understanding the structure of correlations within our current description of nature, based on quantum physics, is a fundamental open problem. In particular, one would like to characterize the set of ...

Orthogonality is a concept often used to describe modular and maintainable software, but it’s more easily understood by way of a case study. In this article, Jens Dietrich demystifies orthogonality ...

This is a preview. Log in through your library . Abstract We prove a generalization of Schur orthogonality relations for certain classes of representations of Gromov hyperbolic groups. We apply the ...

A classification model is easiest to analyze when it has a balanced design. Many of the nice features of balanced designs are retained by error-orthogonal designs, which were introduced in a recent ...

The mathematical study of triangles has just got a whole lot simpler, according to a researcher who says his new theory of trigonometry is easier to use and more accurate. Associate Professor Norman ...
