Soft Skills

A proof of the irreversibility of renormalization group flows in four dimensions

“…In four (and higher) dimensions, we find two separate structures in the spectral decomposition: one corresponds to spin-zero and the other to spin-two intermediate states. A number of branching avenues thus opens as one tries to define a candidate for a c-function [11,12,14,15]. One may in particular conjecture [6] that the natural generalization of the theorem should lie in the spin-zero part of the spectral decomposition of the T T correlator, on the grounds that this is related to the trace of the energy-momentum tensor and thus to the response of the system upon dilatations.…”

“…The couplings are all rendered dimensionless by dividing out the appropriate power of µ (as it is customary in the Wilsonian renormalization group approach). The explicit µ dependence can be traded for the dependence on the only dimensionful physical parameter a, leading to 1 [14] a d da c µ a , g i = β j (g) ∂ ∂g j c µ a , g i . (4.10)…”

“…In construction education, a technical skill could be the completion of a project schedule using a work breakdown structure. Soft skills, alternatively, are more frequently related to skill development in social contexts (Cappelli & Won, 2013). There is no consensus on the definition of soft skills, but they can include communication, critical thinking, problem solving, teamwork, ethics, etc.…”
