Robinson interpolation theorem
Web[Fr]; namely, in Theorem 6.1, under -i0* or -i LM, we show that no logic L between Lxa and Lxx satisfies the Craig interpolation (or the Robinson consistency) theorem, unless =¿ = = . In Theorems 6.2 and 6.3 we prove two results whose effect is practically that any logic L satisfying the Robinson consistency theorem Webelementary proof of the Riemann{Roch Theorem, which is a vital tool to the elds of complex analysis and algebraic geometry.

Formally, the theorem states: If ⊨φ → ψ then there is a ρ (the interpolant) such that ⊨φ → ρ and ⊨ρ → ψ, where atoms(ρ) ⊆ atoms(φ) ∩ atoms(ψ).
