Nuprl Lemma : fps-deriv-neg

[X:Type]. ∀[eq:EqDecider(X)]. ∀[r:CRng]. ∀[f:PowerSeries(X;r)]. ∀[x:X].  (d-(f)/dx -(df/dx) ∈ PowerSeries(X;r))


Proof




Definitions occuring in Statement :  fps-deriv: df/dx fps-neg: -(f) power-series: PowerSeries(X;r) deq: EqDecider(T) uall: [x:A]. B[x] universe: Type equal: t ∈ T crng: CRng
Definitions unfolded in proof :  uall: [x:A]. B[x] member: t ∈ T uiff: uiff(P;Q) and: P ∧ Q uimplies: supposing a all: x:A. B[x] fps-deriv: df/dx fps-neg: -(f) fps-coeff: f[b] crng: CRng subtype_rel: A ⊆B nat: power-series: PowerSeries(X;r)
