Quantum field theory remains among the most important tools in defining 
and explaining the microscopic world. Recent years have witnessed a 
blossoming of developments and applications that extend far beyond the 
theory's original scope. This comprehensive text offers a balanced 
treatment, providing students with both a formal presentation and 
numerous practical examples of calculations. 
This two-part approach begins with the standard quantization of 
electrodynamics, culminating in the perturbative renormalization. The 
second part comprises functional methods, relativistic bound states, 
broken symmetries, nonabelian gauge fields, and asymptotic behavior. 
Appropriate for students and researchers in field theory, particle 
physics, and related areas, this treatment presupposes a background in 
quantum mechanics, electrodynamics, and relativity, and it assumes some 
familiarity with classical calculus, including group theory and complex 
analysis.
