1/N expansions in P(phi2)sub(4-epsilon) theory. Pt. 1
Description
1/N expansions in O(N) invariant one-scale massless P(phi vector2)4-epsilon theory are derived for finite and infinite bare coupling constant. Since superficially relevant (phi vector2)sup(m), m >= 3, interactions can hereby be transformed into interactions irrelevant for large-distance behaviour, the scale-invariant limit theory is universal.

1/N-Entwicklungen in einer O(N)-invariaten, ein-skalaren masselosen P(phi vector2)4-epsilon Theorie werden fuer endliche und unendliche nackte Kopplungskonstante abgeleitet. Aufgrund der oberflaechlichen Bedeutung von (phi vector2)sup(m), m >= 3, koennen Wechselwirkungen so transformiert werden, dass diese fuer das Verhalten in grosser Entfernung keine Bedeutung mehr haben; daher ist die skaleninvariante Granzwerttheorie universal.
