Singular light cone interactions of scalar particles in 1+3 dimensions
Matthias Lienert, Markus Nöth
Here we consider an integral equation describing a fixed number of scalar particles which interact not through boson exchange but directly along light cones, similarly as in bound…

Existence of relativistic dynamics for two directly interacting Dirac particles in 1+3 dimensions
Matthias Lienert, Markus Nöth
Here we prove the existence and uniqueness of solutions of a class of integral equations describing two Dirac particles in 1+3 dimensions with direct interactions. This class of in…
