Nuprl Lemma : bilinear_comm_elim

[T:Type]. ∀[pl,tm:T ⟶ T ⟶ T].
  (BiLinear(T;pl;tm)) supposing ((∀a,x,y:T.  ((a tm (x pl y)) ((a tm x) pl (a tm y)) ∈ T)) and Comm(T;tm))


Proof




Definitions occuring in Statement :  bilinear: BiLinear(T;pl;tm) comm: Comm(T;op) uimplies: supposing a uall: [x:A]. B[x] infix_ap: y all: x:A. B[x] function: x:A ⟶ B[x] universe: Type equal: t ∈ T
Definitions unfolded in proof :  bilinear: BiLinear(T;pl;tm) comm: Comm(T;op) uall: [x:A]. B[x] member: t ∈ T uimplies: supposing a and: P ∧ Q prop: so_lambda: λ2x.t[x] infix_ap: y so_apply: x[s] all: x:A. B[x] squash: T true: True subtype_rel: A ⊆B guard: {T} iff: ⇐⇒ Q rev_implies:  Q implies:  Q
