Basic Quantum Field TheoryKlein-Gordon equation, considered as a classical field equation.This example will already provide the essential lesson to be learnt from the canonical quantization of a linear field theory. The Lagrange density is.To copy the quantization rules of section 1 one has to treat space and time in an asym

General Collision Theorye may regard it as the reason for axiom .. However one should remember that the argument . in Φ.(.) does not have this direct physical meaning though Φ. being formally a free covariant field, also satisfies axiom .. Also it is not obvious at this stage that such a purely space-time-geometric interpr

Charge Superselection Sectorsposition and claim that the net of observable algebras defines the theory completely without need for any additional specification, then we cannot allow any internal symmetry of the observable net in the sense of (III.3.15) with α . ≠ id. So this would also lead to the conclusion that internal symme

Textbook 19921st editiontion its main results of more recent vintage are described in Chapters IV to VI. The first two chapters serve to place this material into context and make the book reasonably self contained. There is a rough tem poral order. Thus Chapter I briefly describes the pillars of the theory existing before
