Understanding of classical field theory underlies understanding of quantum field theory, and this text covers the subject beginning with a chapter on differential calculus on fiber bundles and proceeding with chapters on Lagrangian field theory, Grassmann-graded Lagrangian field theory, Lagrangian BRST theory, gauge theory on principal bundles, gravitation theory on natural bundles, spinor fields, topological field theories, and covariant Hamiltonian field theory.
