2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/38921This is a series of lectures on Monte Carlo results on the non-perturbative, lattice formulation approach to quantum field theory. Emphasis is put on 4D scalar quantum field theory. I discuss real space renormalization group, fixed point properties and logarithmic corrections, partition function zeroes, the triviality bound on the Higgs mass, finite size effects, Goldstone bosons and chiral perturbation theory, and the determination of scattering phase shifts for some scalar models.59 pages (31 figures), LaTeX file (sorry: no PS figures, please ask for a hardcopy), preprint UNIGRAZ-UTP 01-12-93High Energy Physics - Latticetext
