Nuprl Lemma : strict4-concat-map

strict4(λx,y,z,w. concat(map(λb.y[b];x)))


Proof




Definitions occuring in Statement :  concat: concat(ll),  map: map(f;as),  strict4: strict4(F),  so_apply: x[s],  lambda: λx.A[x]
Definitions unfolded in proof :  strict4: strict4(F),  and: P ∧ Q,  all: ∀x:A. B[x],  implies: P ⇒ Q,  concat: concat(ll),  reduce: reduce(f;k;as),  list_ind: list_ind,  has-value: (a)↓,  map: map(f;as),  member: t ∈ T,  uall: ∀[x:A]. B[x],  so_apply: x[s],  prop: ℙ,  guard: {T},  or: P ∨ Q,  squash: ↓T,  is-exception: is-exception(t),  not: ¬A,  false: False
