Description
We consider the infinite volume Dirichlet (or half-Dirichlet) quantum field theory with P(X) = aX4 + bX4 + bX2 - μX(a > 0). If μ unequal 0 there is a positive mass gap in the energy spectrum. If the gap vanishes as μ → 0, it goes to zero no faster than linearly yielding a bound on a critical exponent. (orig.)
Abstract (German)
Wir betrachten die unendlich ausgedehnte Dirichletsche (oder halb-Dirichletsche) Quantenfeldtheorie mit P(X) = aX4 + bX4 + bX2 - μX(a > 0). Ist μ ungleich 0, so enthaelt das Energiespektrum eine positive Massenluecke. Verschwindet die Luecke bei μ → 0, so naehert sie sich dem Nullpunkt nur linear, da ein kritischer Exponent begrenzend wirkt. (orig./AK)Additional details
