Organizing Committee
Abstract

The geometric arrangement of a material’s constituents plays an important role in governing its behaviour. Concepts from discrete mathematics to describe these geometric arrangements, including notions of rigidity and flexibility, can bring fundamental insight into how a material might respond to stress, be designed, be reconfigured, etc. This workshop aims to build connections between the field of mathematical rigidity theory, and other areas of applied mathematics, science and engineering where such ideas might be used.

Rigidity and flexibility form a dichotomy: either a system’s constraints allow for a non-trivial deformation under an external load or they don’t. However, there is a long history, dating to before the Industrial Revolution, of designing mechanisms by starting from a system that has the minimal number of constraints required for rigidity and then removing one of them. One degree of freedom mechanisms obtained this way are a rich class. In recent years, there has been a revival of building deployable mechanisms, inspired by the Japanese arts of origami and kirigami. Generalizing these systems and the mathematics behind their rigidity and deformation has captured the interest of physicists interested in topological materials. On a different lengthscale, our bodies also play out the dance of building rigidity and compliance into different organs and systems, from the packing of cells during embryogenesis to networks of collagen and cartilage that support our skeletons, to the dynamic networks that are formed and broken within our cells. Even continuum systems can have notions of rigidity and flexibility, both intrinsic and extrinsic to their geometry. Beyond materials, the notions of network rigidity can be applied to more abstract networks and geometries, such as those found in data science. Join us in exploring the many ways that rigidity and flexibility influence the world around us and within us.
