Lieb–Mattis theorem

Target entity: Lieb–Mattis theorem
Context triple: [Elliott H. Lieb, notableWork, Lieb–Mattis theorem]

• A. Migdal theorem on Fermi systems
  Migdal theorem on Fermi systems is a result in many-body quantum theory that justifies neglecting certain vertex corrections in strongly interacting Fermi systems, enabling controlled calculations of quasiparticle properties.
• B. Haag’s theorem
  Haag’s theorem is a result in axiomatic quantum field theory showing that the interaction picture cannot be consistently defined for interacting fields in the same Hilbert space as free fields, undermining the standard formulation of quantum field theory.
• C. Birkhoff–von Neumann theorem
  The Birkhoff–von Neumann theorem is a fundamental result in matrix theory and combinatorics stating that every doubly stochastic matrix can be expressed as a convex combination of permutation matrices.
• D. Bohr–Courant theorem
  The Bohr–Courant theorem is a classical result in analytic number theory describing the value distribution of Dirichlet series, particularly the Riemann zeta function, and serves as a precursor to modern universality theorems such as Voronin’s.
• E. Hohenberg–Kohn theorem
  The Hohenberg–Kohn theorem is a foundational result in quantum mechanics that establishes the ground-state electron density as the central quantity determining all properties of a many-electron system, forming the basis of density functional theory.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
