**The ıε prescription in the SYK model**

Razvan Gurau

(Submitted on 24 May 2017)

We introduce an ıϵ prescription for the SYK model both at finite and at zero temperature. This prescription regularizes all the naive ultraviolet divergences of the model. As expected, the prescription breaks the conformal invariance, but the latter is restored in the ϵ→0 limit. We prove rigorously that in the limit ϵ→0 the Schwinger Dyson equation of the resummed two point at low momentum is recovered.
