What is it about?
Confinement of quarks inside hadrons is reflected by unusual analytical properties of quark propagators. In simplified framework of scalar functions, the paper shed some light in this direction and some basic analytical characteristics of QCD Green's functions are calculated and discussed.

Why is it important?
The mathematical tricks shown there are crucial for calculation of QCD Green's functions in Minkowski space. And what is generally important should be decided by others...
Perspectives
Probably this is the first publication that calculation with propagators which have complex conjugated is possible and straightforward in Minkowski space. There are some possible perspectives, if such functions do not violate basic properties required in quantum field theory, e.g. if gauge, Lorentz invariance is maintained.
