Query: Les Houches Lectures on Renormalization Theory and Effective Field
  Theories   These lectures review the formalism of renormalization in quantum field
theories with special regard to effective quantum field theories. While
renormalization theory is part of every advanced course on quantum field
theory, for effective theories some more advanced topics become particularly
important. This includes the renormalization of composite operators, operator
mixing under scale evolution, and the resummation of large logarithms of scale
ratios. This course thus sets the basis for many of the more specialized
lecture courses delivered at the 2017 Les Houches Summer School.
