Description
The gradient-flow formalism constitutes a regularization scheme for ultra-violet divergences which can be implemented both in perturbation theory and on the lattice. This paves unique ways of combining these two approaches to quantum field theoretical calculations in a consistent way. I will present a number of examples where such synergy effects have been explored. The focus of this talk is on the associated higher-order perturbative calculations, and is meant as an encouragement to transfer some of the expertise from conventional higher-order calculations to those in required in the gradient-flow formalism.
