The cut locus appears in various fields of Mathematics as a set of singular points of the distance function or the exponential map on a manifold.

The cut locus has been actively studied in both fields of Analysis and Differential Geometry since H. Poincaré introduced this notion for a point of an analytic surface in 1905. It has been, however, investigated almost independently of each other.

This conference will be a good opportunity for researchers to discuss and share their own knowledge on the cut locus.

Therefore, this conference is open to all researchers interested in this field.
