Description
We review some general aspects of calculations in Minkowski space-time with Functional Methods with a focus on the Functional Renormalization Group.
In particular the implications of having an momentum dependent regulator present are discussed and results for a scalar theory are presented.
Insights from calculations are used to construct improved methods for spectral reconstructions, focusing on the gluon spectral function in Yang-Mills.
Lastly, the calculation of observable, which only require elementary correlation functions in Minkowski space-time is addressed, in particular transport coefficients in Yang-Mills.
