An introduction to non-perturbative foundations of quantum field theory /
This volume discusses fundamental aspects of quantum field theory and of gauge theories, with attention to mathematical consistency. Basic issues of the standard model of elementary particles (Higgs mechanism and chiral symmetry breaking in quantum chromodynamics) are treated without relying on the...
