Φ-derivable Approximations in Gauge Theories *
We discuss the method of Φ-derivable approximations in gauge theories. There, two complications arise, namely the violation of Bose symmetry in correlation functions and the gauge dependence. For the latter we argue that the error introduced by the gauge dependent terms is controlled, therefore not invalidating the method.
متن کاملRenormalization of Self-consistent Φ-derivable Approximations∗
Within finite temperature field theory, we show that truncated non-perturbative self-consistent Dyson resummation schemes can be renormalized with local vacuum counterterms. For this the theory has to be renormalizable in the usual sense and the self-consistent scheme must follow Baym’s Φ-derivable concept. Our BPHZ-renormalization scheme leads to renormalized self-consistent equations of motio...
متن کاملEffective Potential for Scalar Field in Three Dimensions : Ising Model in the Ferromagnetic Phase
We compute the effective potential V eff (ϕ) for one-component real scalar field ϕ in three Euclidean dimensions (3D) in the case of spontaneously broken symmetry, from the Monte Carlo simulation of the 3D Ising model in external field at temperatures approaching the phase transition from below. We study probability distributions of the order parameter on the lattices from 30 3 to 74 3 , at L/ξ...
متن کاملDerivable Type Classes
Generi programming allows you to write a fun tion on e, and use it many times at di erent types. A lot of good foundational work on generi programming has been done. The goal of this paper is to propose a pra ti al way of supporting generi programming within the Haskell language, without radi ally hanging the language or its type system. The key idea is to present generi programming as a ri her...
متن کاملMonotone Difference Approximations for Scalar Conservation Laws
A complete self-contained treatment of the stability and convergence properties of conservation-form, monotone difference approximations to scalar conservation laws in several space variables is developed. In particular, the authors prove that general monotone difference schemes always converge and that they converge to the physical weak solution satisfying the entropy condition. Rigorous conve...
