Özet / Abstract : I would like to explain how to use the exact renormalization group (Wilson-Polchinski differential equation) to construct QED perturbatively.  I first introduce the necessary tools using a real scalar theory as a concrete example.  I then explain how to construct QED by imposing the Ward-Takahashi identity to the solution of the ERG differential equation.  I end the talk by deriving the Khalatnikov-Landau equation for the gauge parameter dependence of the correlation functions.
