Abstract [en]

Let (R,m) be a local ring which is a Golod ring and let k = R/m. We prove

that the Yoneda algebra A = Ext*_R(k, k) is coherent and that the bigraded (commutative) algebra

Ext*_A (k, k) is Noetherian. We give details of these results which enable us to prove that certain

formal power series in one or two variables are rational.
