∀[X:Type]. ∀[r:CRng]. ∀[c:|r|]. ((c)*0 = 0 ∈ PowerSeries(X;r))
Proof
Definitions occuring in Statement :
fps-scalar-mul: (c)*f,
fps-zero: 0,
power-series: PowerSeries(X;r),
uall: ∀[x:A]. B[x],
universe: Type,
equal: s = t ∈ T,
crng: CRng,
rng_car: |r|
Definitions unfolded in proof :
uall: ∀[x:A]. B[x],
member: t ∈ T,
uiff: uiff(P;Q),
and: P ∧ Q,
uimplies: b supposing a,
all: ∀x:A. B[x],
crng: CRng,
rng: Rng,
true: True,
fps-zero: 0,
fps-coeff: f[b],
fps-scalar-mul: (c)*f,
infix_ap: x f y,
squash: ↓T,
prop: ℙ,
subtype_rel: A ⊆r B,
guard: {T},
iff: P ⇐⇒ Q,
rev_implies: P ⇐ Q,
implies: P ⇒ Q
