Abstract
We consider three rigid balls moving on a plane and investigate their multiple collisions (i.e., the three balls collide at the same time). This is a 3D problem because balls may jump. We develop a predictive theory based on the idea that the system made of three balls and a plane is deformable. As shown by the examples, the theory accounts for the physical properties of multiple collisions and its main feature is the presence of non local interactions.
