AbstractLet A be a real Bose or Fermi one-particle operator with ∥ A ∥ ⩽ I. Using Kaplansky's density theorem, a simple proof is given of the fact that Γ(A), the operator in Fock space induced by A, is positivity preserving in the relevant L2-space

Euclidean dense matter generically suffers from the fermion sign problem. However, we argue that the...
