The construction of an effective action for many field theories requires
some form of renormalization. This talk will be on the inductive
position space renormalization procedure developed by Costello for this
purpose. We will introduce the procedure, using the example of a scalar
field theory for simplicity, and show how the procedure was clarified
for closed manifolds and extended to a class of compact manifolds with
boundary.
