4D vs. 2D

  1. Jan 6, 2013 #1
    The combination of special relativity and quantum mechanics in a single framework makes our understanding of such systems to be true only in 4D, Minkowski space...I have noticed that recent published work concerning 2D systems and I am not sure about this reduction of 4D to only 2D, does it mean evaluating path integrals (e.g. correlation functions) by considering (1,1)=(time,space) in order to simplify the calucualtions?
