A Geometry of Specialisation [PDF]
The Economic Journal, 2002 Division of labour models have become a standard analytical tool, along with competitive general equilibrium models (Ricardian, HOS, Ricardo-Viner), in public finance, trade, growth, development and macroeconomics. Yet unlike the earlier models, these models lack a canonical graphical representation.

GEOMETRY OF SPACETIME AND FINSLER GEOMETRY
International Journal of Modern Physics A, 2009A central assumption in general relativity is that the underlying geometry of spacetime is pseudo-Riemannian. Given the recent attempts at generalizations of general relativity, motivated both by theoretical and observational considerations, an important question is whether the spacetime geometry can also be made more general and yet still remain ...

Proceedings of the 2017 CHI Conference Extended Abstracts on Human Factors in Computing Systems, 2017
Motivated to provide 6- to 11-year-old children with a way to experience mathematics as collaborative, tangible, and concrete, we present Geometris, a collaborative embodied geometry game. As shapes are projected onto the floor, players recreate those shapes on a 6x6ft interactive mat.

Some structures are more suitable for self-organization through the Darwin-Wallace mechanism of variation and selection than others. Such evolutionary adaptability (or evolvability) can itself evolve through variation and selection, either by virtue of being associated with reliability and stability or by hitchhiking along with the advantageous traits ...

Orthogonal geometry, metric geometry and ordinary geometry
1994In Desarguesian (plane) geometry which takes Hilbert’s axioms of incidence H I, (sharper) axiom of parallels HIV, the axiom of infinity D∞ and Desargues’ axioms D as its basis, one can uniquely determine a Desarguesian number system N, called a geometry-associated Desarguesian number system, as has been exhibited in the previous sections.
