Nuprl Lemma : neg_id_fps

[X:Type]. ∀[r:CRng].  (-(0) 0 ∈ PowerSeries(X;r))


Proof




Definitions occuring in Statement :  fps-neg: -(f) fps-zero: 0 power-series: PowerSeries(X;r) uall: [x:A]. B[x] universe: Type equal: t ∈ T crng: CRng
Definitions unfolded in proof :  uall: [x:A]. B[x] member: t ∈ T fps-zero: 0 fps-neg: -(f) power-series: PowerSeries(X;r) squash: T prop: crng: CRng rng: Rng true: True subtype_rel: A ⊆B uimplies: supposing a guard: {T} iff: ⇐⇒ Q and: P ∧ Q rev_implies:  Q implies:  Q
