Algebraic Quantum Field Theory, Perturbation Theory, and the Loop Expansion
The perturbative treatment of quantum field theory is formulated within the framework of algebraic quantum field theory. We show that the algebra of interacting fields is additive, i.e. fully determined by its subalgebras associated to arbitrary small subregions of Minkowski space. We also give an algebraic formulation of the loop expansion by introducing a projective system A(n) of observables...
متن کاملAlgebraic Quantum Field Theory∗
Algebraic quantum field theory provides a general, mathematically precise description of the structure of quantum field theories, and then draws out consequences of this structure by means of various mathematical tools — the theory of operator algebras, category theory, etc.. Given the rigor and generality of AQFT, it is a particularly apt tool for studying the foundations of QFT. This paper is...

متن کاملAdaptive Perturbation Theory: Quantum Mechanics and Field Theory
Adaptive perturbation is a new method for perturbatively computing the eigenvalues and eigenstates of quantum mechanical Hamiltonians that are widely believed not to be solvable by such methods[1]. The novel feature of adaptive perturbation theory is that it decomposes a given Hamiltonian, H , into an unperturbed part and a perturbation in a way which extracts the leading non-perturbative behav...
متن کاملQuantum Field Theory, Grassmannians, and Algebraic Curves
This paper is devoted in part to clarifying some aspects of the relation between quantum field theory and infinite Grassmannians, and in part to pointing out the existence of a close analogy between conformal field theory on Riemann surfaces and the modern theory of automorphic representations. Along the way we develop a multiplicative analog of the usual additive Ward identities of current alg...
