Concurrent synchronization and covariation in upper extremity joint angles during a reciprocal aiming task

Abstract The ecological-dynamical approach holds that movement is self-organized, implying a circular causality between the kinematics of the end-effector and the coordination of degrees of freedom (DOF) into synergies. Yet, how this circular causality manifests itself in redunda...

Rotation groups, mediangle graphs, and periagroups: A unified point of view on Coxeter groups and graph products of groups

In this article, we introduce rotation groups as a common generalisation of Coxeter groups and graph products of groups. We characterise these groups algebraically by presentations ( periagroups ), and we propose a combinatorial geometry ( mediangle graphs ) to study them. As an...
