描述We summarize the situation regarding non-polynomial Lagrangians: I should make the qualification that an enor­ mous amount of verification is needed before the problems of renormalizability are all sorted out, but one may ten­ tatively state: 1) All matrix elements are finite for theories where the Dyson index D is less than two. 2) For the cases when D=2 or 3, counter-terms have been explicitly written which absorb all infinities and the theories are renormalizable. 3) Mixed theories of polynomial and non-polynomial fields appear to be renormalizable provided the Dyson in­ dices separately and jointly fulfill renormalizability criteria. We believe that weak interactions, chiral La­ grangians and Yang-Mills theory fall into this class though detailed proofs have not yet been constructed. 4) It seems likely that to each order in the major coupling (and to all orders in the minor coupling}the S­ matrix elements, as computed by methods outlined, satisfy the necessary unitarity and analyticity requirements.

,Some Exact Results on π π Scattering,e ability to produce measurable numbers, is approximately a constant. So the few people who want to obtain physical results, by purely deductive means, starting from postulates which are not obviously inconsistent with one another have a very hard time. One may be sometimes tempted to think that the

Some Recent Work in Regge Theory: Regge Cuts, The Absorption Model and Glauber Theory,one using perturbation theory. A derivation is given of the cut structure that arises from the absorption model and from the Glauber model of deuteron scattering. The validity of this derivation, and of these models, is then examined.

,Veneziano — Like Model for A Two-Current Amplitude,ts. It is found that when one incorporates certain desirable features, in particular the correct Fubini-Gell-Mann fixed pole at j=l, the model automatically satisfies the Bjorken scaling law. It is shown how the model may be extended to describe deep inelastic electron-proton scattering.

Differentiable Manifolds, the domain of c,ϕ the coordinate mapping of c. For each pεU we can write (see Fig. 1).We call (x.,...,x.) the local coordinates of p in the chart (U,ϕ). The notation can be made more explicit by writing x.,...,x. in the form.or, in short, x(p)

The Construction of Physical States in Quantum Field Theory,ther give colorful nonsense answers (infrared, ultraviolet catastrophes) or else they would be butchered beyond resemblance to anything that the purists would call field theory. In those days it used to be a party game to guess at what the miracle cure might be,the “totally new idea” that was needed

The O(3,1) Analysis of Currents and Current Commutators,ator connecting two (in this case: reducible unitary) representations of the group SL(2,C). In these lectures we review first the representation theory of the group SL(2,C). This enables us to derive a decomposition theorem for covariant operators with heuristic arguments. By this theorem we can dec
