Abstract
We consider techniques (based on an ultraviolet cutoff) used to prove that
the pure boson (
field theory is trivial and apply them instead to
the dynamically generated quark-level linear sigma model. This cutoff
approach leads to the conclusion that the latter field theory is in fact
nontrivial.
