Nonperturbative Quantum Field Theory on the Lattice
  These lectures provide an introduction to lattice methods for nonperturbative studies of quantum field theories, with an emphasis on Quantum Chromodynamics.   Lecture 1 (Ch. 2): gauge field basics   Lecture 2 (Ch. 3): Abelian duality with a lattice regulator (Ch. 4): simple lattice intuition   Lecture 3 (Ch. 5): standard methods (and results) for hadron spectroscopy   Lecture 4 (Ch. 6): bare actions and physics   Lecture 5 (Ch. 7): two case studies, mass of the glueball and $\alpha_s(M_Z)$
