 While Batterman and Rice claim that explanations that depend on renormalization group techniques are not causal, Reutlinger 2014 insists that causal factors are still present. But Reutlinger also admits that non-causal factors are crucial due to the role of mathematical operations. He thus links these cases to Lange’s class of distinctively mathematical explanations (Lange 2013c, see below). For more on renormalization techniques and mathematical explanation see Batterman 2010b, Reutlinger 2014, 2017a and 2017b, Povich 2016, and Morrison 2018.
