 One important area for interpretive investigation is the existence of a continuum of unitarily inequivalent representations of an algebra of observables. Attitudes towards unitarily inequivalent representations differ drastically in the philosophical literature. In (Wallace 2006) unitarily inequivalent representations are not considered a foundational problem for QFT, while in Ruetsche (2011), Lupher (2018) and Kronz and Lupher (2005) unitarily inequivalent representations are considered physically significant.
