“Singularities” are points in a geometric region which are different from most nearby points in the region. They are points of particular interest, arising in many areas of science such as biology, chemistry, physics and social science. They also lead to applications in technological domains, for example in robotics, control theory, optic, medical imaging, etc. Their study uses many mathematical tools. One of these tools is what is called “bi-Lipschitz geometry”, which permits alteration of a geometric object by applying limited local stretching and shrinking. For example, a bi-Lipschitz change to the geometry of a knife preserves the sharpness of the knife, but may turn a dinner knife into a butter knife.

Applying bi-Lipschitz geometry to singularities retains their basic structure while making them much easier to classify and therefore easier to work with. Despite this, it is only fairly recently that bi-Lipschitz geometry has been applied much in singularity theory, but its use has grown rapidly in the last decade as an increasing number of researchers are starting to work with it. It is a powerful tool for a variety of mathematical problems.
