Query: Multiplicative properties of Quinn spectra   We give a simple sufficient condition for Quinn's "bordism-type spectra" to
be weakly equivalent to strictly associative ring spectra. We also show that
Poincare bordism and symmetric L-theory are naturally weakly equivalent to
monoidal functors. Part of the proof of these statements involves showing that
Quinn's functor from bordism-type theories to spectra lifts to the category of
symmetric spectra. We also give a new account of the foundations.
