Both authors work in the Department of Field Theory at the Marian Smoluchowski Institute of Physics, Jagiellonian University, Cracow. They are experienced academic teachers specialized in theoretical and mathematical physics. Professor Henryk Arodz has published research papers on the Yang - Mills fields, topological defects, and several other topics in field theory and quantum mechanics. Dr. Leszek Hadasz has investigated, among other things, exactly solvable models with (super-)conformal symmetry and strings in non-critical dimensions.

• Introduction.- The Euler-Lagrange equations and Noether's theorem.- Scalar fields.- Vector fields.- Relativistic spinor fields.- The quantum theory of free fields.- Perturbative expansion in the phi44 model.- Renormalization.- Renormalization group.- Relativistic invariance and the spectral decomposition of G(2).- Paths integrals in QFT.- The perturbative expansion for non-Abelian gauge fields.- The simplest supersymmetric models.- Anomalies.- Appendix: Some facts about generalized functions.

From the reviews: "This new and modern textbook stands out for its pedagogy ... and is based on an introductory course given to students at the University of Cracow in Poland. At the same time it is an excellent textbook for a first encounter with quantum field theory, treating a variety of topics that are only touched on in previous books with similar title."
