Abstract

Størmer proved a theorem on the integral decomposition of symmetric states on a C*-algebra ⊗B. Motivated by problems in statistical mechanics, we define symmetric states on a composite algebra A⊗(⊗B) and extend Størmer’s theorem to this situation. Applications to spin-boson models are sketched.
